Just in case you’ve been reading around and researching the many terms and topics that concern surround sound and the many surround sound systems on the market today, I thought it might be a good idea to explain some of the terminology that is floating around. First of all there are many initials names and numbers floating around when it comes to surround sound technology and equipment, it’s no wonder that many of us mere mortal consumers are more than a little confused by it all. Hopefully the information you find below will prove helpful as you weave through the wired jungles of modern sound technology.

The first and probably most common thing you will see in these circles is Dolby Digital. While there are many complicated definitions of this term the one that will matter most to you, as a consumer is that right now it is the leading format on the market when it comes to processing the digital data that your system will need to process. There are better brands such as DTS when it comes to musical sound for this function but the vast majority of television broadcasts and DVDs are optimized for Dolby.

Speaking of DTS, at the moment they are Dolby’s primary competition. While most items you find on the market such as DVDs are viewable in both DTS and Dolby you need to make sure that they system you purchase whether Dolby or DTS can read both formats for those times when your favorite flick just might not be enhanced for both.

Now perhaps the most confusing of terms when it comes to surround sound systems would be 5.1. It looks so innocent just sitting there but most people are ready to pull out their hair when they realize that it really stands for a system that includes 6 speakers rather than five. The “.1″ in the name refers to the frequency of the subwoofer (or Low Frequency Effects-LFE), which is .1. Despite the existence of ‘better’ systems on the market today, most movies are optimized for this particular set up so this will be of the most value to you with the current products on the market rather than spending more for systems that the DVD makes haven’t yet caught up with.

DTS ES refers to a format commonly referred to as 6.1. In this format there is one additional speaker moved to the center rear of the configuration and the two-rear left and right speakers are moved forward. And THX EX 7.1 is what happens when you add yet another speaker. There aren’t too many films at the moment that use this particular format some notable exceptions would be the Star Wars movies. This means that movies haven’t really caught up to the technology of either of these systems but they are on the market and some people simply must have them. I recommend going with a superior 5.1 channel surround sound system for the time being and adding speakers when there are more reasons to do so.

This list is by no means exhaustive but will give you a basic overview of the information that is relevant to you as you look into the various surround sound systems on the market today. You shouldn’t have to weed through volumes of confusing terminology in order to find out that the system you are interested in actually has 6 speakers rather than 5. My hope is that you can go in armed with basic knowledge that will help you make an informed buying decision.

In case you hadn’t figured it out by now, surround sound is named as it is because the sound literally surrounds the listener. While there have recently been significant leaps and bounds in this technology there was a huge gap in time between the introduction of this technology and the significant improvements we have seen in recent years. This is especially true when the evolution of sound technology is compared to how fast the world of video has evolved over the last three decades.

There are many different formats on the market today. This can be confusing for many consumers though the good news is that most devices that interpret the formats do so automatically. In other words, you won’t need a PhD in terminology in order to enjoy the latest blockbuster hit to come out on DVD with your surround sound system. You will however need a good AV receiver and even better speakers in order to get the maximum enjoyment from your home theater and surround sound system.

If you are simply curious or like to know a little about a lot, then you just might find some of the following explanations for common surround sound formats to be useful. Dolby Digital AC-3 is by far the most commonly seen surround sound format. It is a 5.1 channel format (this means five speakers plus one subwoofer). This is what most DVDs will include and some programs that are found on digital cable or satellite channels will have this type of surround sound as well. You can use Dolby Digital for older mediums that do not include surround sound in their format, as surround isn’t required in order to use the system.

Pro Logic is a system used by Dolby in order to translate or decode the signals from other mediums such as old videocassette tapes or television broadcasts. This is becoming widely known for its ability to take two speaker sounds and turn them into shockingly realistic surround imitations.

DTS is the largest competitor for Dolby when it comes to sound. DTS is this company’s answer to Dolby Digital 5.1 surround sound. This is mostly seen only on DVDs.

DTS-ES is the above-mentioned company’s answer to Dolby’s 6.1 surround system (this is 6 speakers plus 1 subwoofer). Of course DTS is also going to have their own answer to Pro Logic and that answer would be DTS NEO:6, which is said to produce great imitations of surround sound from existing 2 channel mediums very much like Pro Logic.

You may be wondering why we went through all of this information and the primary reason is so that you know there is a difference and you purchase equipment and DVDs that are compatible with one another. Failure to do so could result in a sound that is less than desirable. Most systems will at the very least support both Dolby Digital and DTS, however, you should make sure that you are aware of the format your system requires from the start in order to make the proper decisions when purchasing.

Much like anything in life the proper formats and surround sound system comes down to a matter of choice. The more speakers (such as you would find in the 6.1 or 7.1 surround systems) will present a great quality of sound than fewer, however poor quality speakers can completely ruin the beauty of the sound of your surround sound system. Your speakers should be your single largest investment when it comes to building your ideal surround sound system.

There are many things that go into creating not only the perfect surround sound system for your home but also the perfect surround sound set up. Do not get so caught up in researching these systems online that you neglect to walk into your local stores and actually hear the sound systems you are considering for purchase. There is noting like hearing the quality of the sound to help you make your final selection.

One thing that often gets overlooked during the process of purchasing pieces, parts, and components for your surround sound system is the importance of cables to the overall sound of your system. It makes absolutely no idea to buy top of the line speakers and excellent quality components only to use substandard el cheapo cables with which to connect them to one another. Unfortunately we see this every day and it causes problem with the quality of the sound that leads over time to a total and complete dissatisfaction with the quality of sound your system provides.

There are other considerations when it comes to cables such as aesthetics, which will also affect the price when it comes to your system. I strongly encourage you to seriously consider what level of cabling and wires you can and cannot live with before you purchase your surround sound or home theater system, as both tend to be very wire and cable intensive. There are however things you can do to tame the tangle before it overtakes your home and one of my first recommendations is to seriously consider the value that going wireless would add to your system.

Wireless speakers eliminate the need for a good portion of the wires and cabling that are typically part and parcel of the lot when it comes to good sound systems. Going wireless for me is far preferable to drilling holes into the walls and running the wires through and having a rat’s next of speaker wires overhead in my home is simply not an option. Of course everyone has different priorities when it comes to their surround sound or home theater systems and some people aren’t all the considered about wires and cables. If you are not one that bothers then that is no problem either.

Unfortunately the wires and cables in a home theater or surround sound system are not limited to the speakers alone and while going wireless for the speakers is often financially feasible it’s an entirely different ball park to go wireless for the whole kit and caboodle. For this reason there are all kinds of nifty tips and tricks for taming a mess of wires and keeping things organized and tidy behind the scenes. Among my favorites are these new power strips that allow you to color code and label which cord goes where. These strips are also great because they offer surge protection for your costly electronic equipment.

In addition to having the power strips labeled and organized you can purchase PVC piping and run all the cords down one tube in order to reach the power strip. You can also paint the tube in order to blend in with your wall if you are concerned about the aesthetics of the tube. I personally like this option for keeping all the chords in one spot rather than having them run haphazardly along the back of your other electronic components. It simply looks neater and more organized and your friends and family will be impressed at your cleverness for thinking of it.

If you have a certain disdain for over organization or having things too terribly tidy you can always opt for these Velcro ties that you simple use like the old sandwich bag ties. They can keep several chords together so that you aren’t constantly having to work around them and yet allows you easy access to the chords should you find a sudden need for access or get the urge to rearrange or change settings and situations.

While it doesn’t take rocket science to tame the wild tangle of chords that sometimes invade of entertainment space, it often helps to have a few tricks up your sleeve when confronting the seemingly endless stream of wires that are part of the average home theater or surround sound system. Hopefully you will find that some of these suggestions and tips will be helpful in your home.

A good home theater and surround sound system for your movie enjoying pleasure is a rather large investment for the common movie buff-at least if you are purchasing a really high quality system for your home theater or media room. This isn’t to say that you cannot find decent surround sound systems for small spaces that come with much lower price tags than you will ordinarily find on the market. In fact, there are many ways in which you can buy a decent surround sound system for a small room even if you are limited by budget constraints.

Second Hand Systems

Buying second hand from Ebay carries some degree of risk but a reputable seller is often a good place to start. There are some people who simply can’t stand to have technology that is 6 months or even 6 days for some matters, old. Their loss is your gain as you can score a really nice surround sound system, speakers included at amazingly low prices if the bidding works in your favor and you know a little about brands and quality. Pawnshops and electronics consignment stores are other good places to find bargains on this particular sort of equipment.

Buy Boxed Sets

I’m typically opposed to box sets when it comes to electronics as there have been many instances in the past where these were merely a method of pawning off inferior goods on an unsuspecting public. However, big names such as Bose have gone over to the dark side so to speak and are beginning to offer box sets of surround sound speakers at surprisingly and amazingly reasonable price tags. There are cheaper brands than Bose, don’t get me wrong, I use them as an indication of the wide variety and standards you will find in surround sound speaker systems that come in box sets today. The good news is that you can get really good prices on speaker systems such as this if you are willing to shop around.

Compare Prices

It really does pay in this day and age to do just that. Even if you have a favorite retailer chances are that you could get a better price through them by doing a simple search online and looking for a lower advertised price. If not, it might be worth your while to go with the Internet provider this time and save your money for DVDs and music with which to enjoy your new surround sound system. I also recommend seeing what local competition has to offer; you’ll be amazed at some of the wonderful bargains you can find by walking into a store on any given day. I know that stores like Circuit City have great bargains on featured items during the week in order to boost sales. You never know when one of those items might be an outstanding surround sound systems or a phenomenal set of speakers.

Wait it out

If you have your heart set on one surround sound system and nothing else will do, then it may be in your best interest to wait until the price drops. In electronics terms that often means waiting about 6 months or until the next consumer expo event (this is when all the new technology is introduced, which makes all the existing technology drop its prices in order to seem more appealing). Both of these options may seem unappealing but can mean very real and very significant savings on your part if you are willing to wait in order to get what you really want. Not only does this give you time for the prices to decrease but also for the size of your savings to increase.

While shopping on a budget isn’t always the preferred method it is very possible to get a decent home theater or surround sound system for your home even if you are working within the limits of a seriously impaired budget.

If you are one of the many people around the world who loves the sound quality of watching movies in theaters but hates the hassles (crying babies, people talking, cell phones ringing, etc) of actually going then I hope you are seriously contemplating the value that a home theater or surround sound system could bring to your movie enjoyment. In fact, a good surround sound system cannot only improve your overall enjoyment of blockbuster hits but also your favorite music and video games as well. Surround sound is far more than a tool for watching movies at home, it is an entirely new way to look at and listen to your television in general.

You do not have to begin your home theater or surround sound experience with a top of the line piece of equipment. It is quite possible to start small with a surround sound system and build a better system as you go. In fact, I seriously recommend that people invest heavily in speakers from the beginning and sacrifice the number of speakers in favor of better quality speakers. In addition to this there are many box kits out there that are designed for almost any budget on the market. You can find box kits for everything from basic surround sound systems to home theater in a box. If you are seriously considering the enjoyment this can bring into your home there is no time like the present to start checking out your options.

I never recommend simply walking into the store and purchasing the first kit you find though you are certainly welcome to do just that. I feel that you might walk away from the experience a little jaded however and highly suggest that you go to a local retail center that has sound rooms set up in order to listen to the many options that are currently on the market and compare the sound and the quality of the sound within those items in your price range. I suggest that you start on the low side and work your way up rather than starting at the high end and working your way down.

When you find the quality of sound you are most comfortable with, this is the system I recommend you go home and research. Compare prices online to see if you can find any major values and bargains. The Internet is usually full of good deals for consumers that are willing to sort through many companies that market online. While the Internet is the land of opportunity for some, I also recommend that you take the lowest price you find online to your local retail store and see if they can match it or throw in a few perks to sweeten the deal. You could find some interesting deals by doing this and it costs nothing to try and could save you money in the long run.

The point is to get the best system your money can buy (without sending you to the ‘poor house’ in the process). Once you have decided on the system you want all bets are off when it comes to finding the best price. We live in a consumer driven marketplace and as a consumer you do have control over where your money is spent and whether or not you are willing to pay the price of spending your money elsewhere.

You know the quality you expect, as you’ve listened and compared in the stores, and you know the price that you are willing to pay for that quality. Most consumers are learning this fact and willing to make concessions in order to compete with those companies that operate online. See what your local retailers can offer you and if they can’t match what you’ve found online you should be willing to go with the online service. This is a great way for you as a consumer to know what you are getting and feel as though you’ve gotten a good deal in the process. More importantly you get to bring the theatrical experience you love so much into your very own living room. Now the only kids crying over your movie will be your own.

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the providers income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.
Another great thing about satellite radio is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The satellite radio signal is digital, which means that you will get crystal-clear sound wherever you go.

Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receivers display.
All satellite radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying beep sounds.
Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to satellite radio online on your computer.

If you still are not convinced on why you should pay money for something that you can get for free, think about how much time you have wasted listening to commercials and all kinds of other boring stuff on terrestrial radio programs. Traditional radio is not free, despite the popular belief. It is time-consuming and irritating because you have to listen to five minutes or more of commercials so that you can finally hear a song you like. The satellite radio subscriptions are very affordable and, for around 13 dollars per month, you get exactly the programs you want, which you can listen to wherever you are, at the best sound quality.

Satellite radio is great for you especially if you travel a lot. If you are traveling across the United States of America, for example, you can listen to the channel or channels you want during your whole trip, without losing signal or getting static. If you have a traditional radio, you will have to keep changing channels every hundred miles, but if you are using satellite radio you do not have to do that because the geographically availability of programs is not a problem. Satellite radio subscribers will soon get the chance to watch video programs as well. Both Sirius and XM services have announced their intention of introducing in the near future a variety of video satellite channels that will have some of the great advantages that are currently available to satellite radio: commercial free programs, great quality of sound and vast geographical availability.

The idea of Americas biggest two satellite-radio joining forces has been up in the air for almost four years. Although XM had a years start, Sirius came back on the market, eventually with both companies sharing the market in half. So, whats to choose? XM or Sirius?
First things first. XM and Sirius are based on the same principle, each of them providing music, news, sports, etc. on their channels, but, every service has its ups and downs so we will try to discuss it in this present article. A careful analysis shows that XM Satellite Radio provides a total of 136 streams, where two are premium channels (Playboy and High Voltage), twenty-one are traffic and weather based channels and nine are sport-dedicated ones. On the other hand, Sirius offers a total of 119 streams, the premium streams not being available. Lets take a closer look now on two music and news – of the categories that the two major satellites are battling.

Music streams comparison

The number of music streams that both services offer is pretty much the same: 65 on Sirius and 68 on XM Satellite Radio but the difference is not in the number, but in the music genres that the radios offer.

Music Decades

XM is the absolute champion in providing the music by decades because you can listen to the 40s music, service not available on Sirius. Still, you can listen to the 90s hits together with the current hits on Sirius Satellite Radio, which is an interesting feature.

Music Country

Ride em cowboy!. Even if youre not a cowboy, you can listen to country-related songs on both Satellites. Classic country or country hits are to be heard as well as alternative country or country mixes, the last two features being available only on Sirius Satellite Radio. Regarding the number of streams that both Satellites offer, XM offers a total of five streams and Sirius offers four, the champion in this category being XM due to the quality and the quantity of music being played.

Music Rock

If you are looking for sex, drogs, and rock and roll, Sirius and XM Satellite Radios can only offer you rock and roll, on a number of 14 streams on XM and 15 streams on Sirius. The rock subgenres are to be found in a large number on the stations, overall each service being very strong in this category.

Music – Dance and Latin

If you want to boogie, you can do that on both Satellites, listening to one of the six streams provided by Sirius or four streams provided by XM. Be careful though, because you can become a clubber maniac! And if youre strong enough, the Latin pop stream, Mexicana and tropical music streams can really drive you crazy. XM Satellite Radio as well as Sirius Satellite Radio offer three streams.

Music Other genres

Regarding other genres, both satellites really look up to their prestige, offering hours of hours of music, from Classical to Jazz, even Urban (Sirius feature). Both stations offer high quality tunes, making it worth all the money.

News Streams Comparison

Lets skip to another interesting topic, news. CNN, FOX, CNBC, Bloomberg, MSNBC and many more news stations are being offered for listening in different languages. The number of streams is again near-by, XM offering a number of 11 news streams, not like Sirius, which offers 13.

Bottom line

Its pretty hard to say which station is better, XM and Sirius being tied musically but in news and sports, Sirius holding the edge. To make a little joke, if you are a fan of Stern go with Sirius, if you like Q&A go XM. Anyway, its hard to say which one is better, but, what can I say is that both Satellites are worth paying for.

XM Satellite Radio Inc. is one of the major players in the satellite radio industry, with over 2 million subscribers and spreading all over the American territory. XM Satellite Radio Inc. deliver over 120 channels of radio to an ever expanding customer number. Here are some of the characteristics of XM Radio:
Corporate headquarters: Washington, D.C.
Date of launch: November 12, 2001
Satellites in service: 3
Available satellite radio channels:150
Monthly subscription cost:$12.95

XM Satellite Radio Inc. is the owner of one of the 2 FCC approved licenses for delivering digital radio in the United States. Since it only shares the field of Satellite Digital Audio Radio Services (SDARS) with Sirius Radio, XM Satellite Radio Inc. has plenty of room to develop and expand. 2001 was the year when XM Satellite Radio Inc. began broadcasting progress was slow at first, but soon after satellite radio began skyrocketing as a social and economical phenomenon. Since it was the first national digital satellite radio service provider, XM Satellite Radio Inc. captured an important share of the market and started offering music programs and other types of shows and channels like talk shows, sports, comedy, science and news. XM Satellite Radio Inc. owns the most impressive digital radio equipment and facilities, boasting over 82 end to end broadcasting studios. The digital radio used by XM Satellite Radio Inc. is encoded using the complex CT-aacPlus technology which is broadcast in 128kb/sec format very close to CD quality. The signal produced by using this technology makes the transmission much clearer and more accurate than any analog radio provider could ever offer. There are no noise disturbances that were often present with FM and AM broadcasts and the transmission is crystal clear. The fact that the signal is received in digital form solves many noise disturbance problems and the output is close in fidelity to the original track.

The XM Satellite Radio Rock and Roll satellites

XM Satellite Radio uses two of the most potent commercial satellites, which are constantly orbiting the Earth at a height of 22 300 miles. The two Boeing HS-702 satellites have some inspired names – “Rock” and “Roll”. The first of the two satellites, Rock, was launched in orbit on March 18, 2001 and is currently positioned at 85 degrees West Longitude. It services the western half of the United States and complements the range and area of coverage of its younger brother Roll. Roll was launched on May 8, 2001 and it currently positioned at 115 degrees West Longitude, and it services the eastern part of the United States. The combined coverage of the two satellites spreads beyond US borders and reaches areas like Canada or Mexico. This is an interesting feature of satellite radio, as it further points out the benefit of not having to switch radio stations during long trips or while moving over the border. For emergency purposes, the company has third redundant HS-702 satellite on the ground, ready to replace Rock or Roll if any of them fails. Both satellites use different transmission frequencies which prevents interference.

Using the XM radio transmission

The powerful broadcast signal used in satellite radio means that you only need a small receiver in order to be able to listen to digital radio. These small omni-directional antennas are similar to GPS devices and do not require mechanical pointing in order to receive the signal. Some of the new features of satellite radio refer to the extended broadcast information abilities. XM offers information about the broadcast type, and includes the song title, artist, and genre of music. As a recent improvement, XM radio also started broadcasting weather related news and traffic statuses on their programs. In order to use the XM Radio programming you need a XM Radio receiver, an antenna and a subscription to the XM services. Different music equipment producers have teamed up with XM Radio in order to allow adding XM broadcasting to their already existing devices. Some vehicle manufacturers are also offering XM Radio as a factory installed option.

* Unsigned: unsigned bands
* XMU, XM Caf, the Loft, XM Music Lab: soft rock, eclectic rock and any other rock type that doesnt fit anywhere else
Urban rap and hip hop, both modern and from the 80s.
Jazz & Blues 6 channels altogether out of which four are commercial free
Dance techno and trance music rules here, but you also get some disco music
Latin 5 commercial free channels of Latin, Spanish and Mexican hits.
International Music 5 channels of music from around the world. You might find these five channels a welcomed break from all the music you are used to. Fresh music from around the world is presented daily.
Classical classical music from both famous and less renown classical musicians. You get the XM Pops, XM Classics, Vox and Fine Tuning. As you would expect, all 4 channels are commercial free.
Kids – Radio Disney and XM for Kids. Excellent programs that will keep your kid busy and happy for a long time.
News you will get Fox News, CNN Headline News plus other TV related news channels. They feature XM commercials.
Sports you will get channels like ESPN Radio, ESPN News, Fox Sports Radio, Sporting News, NASCAR Radio. These channels cover most of the important sporting events in the United States but you can also get international sports news here.
Comedy both family oriented comedy stiles and uncensored comedy bits. These channels are commercial free, which is really enjoyable.
Talk & Variety there are different talk channels and shows that are really engaging, such as E! Entertainment Radio, ABC News and Talk, Buzz XM, Ask channel, The Power and Family Talk. However, these channels have plenty of commercial time which is a bit of a disappointment from a paid subscription service.
Variation and content

These are the things both XM Radio and Sirius are after. With over 100 channels, each provider is able to identify and target all the important age and social groups in the United States. When it comes to music, there are extremely specialized channels on XM Radio, so the consumer knows exactly what kind of music they will run into on that particular channel. The kids channels are pretty good and the sports channels are also ok. If you like to get your news TV style, XM Radios choice of channels is also interesting. The fact that commercials are present is not that bothering, as they are only allowed to play 6 minutes of commercials per hour. However, some of the music channels are kept 100% commercial free, which is good news for music fans who do not want their audition to be interrupted by intrusive commercials.

Satellite radio is often considered one of the biggest improvements in broadcasting since the introduction of the FM band. Satellite radio is also called subscription radio or pay-radio because it is only available trough subscription to one of the satellite radio providing companies. Satellite radio follows a concept similar to cable television by providing a very wide range of programs which are not available in the traditional FM or AM format for a fee.

Satellite radio uses satellites to deliver radio programs to subscribers. The radio signal is broadcasted from Earth based stations to communicational satellites, which then redirect the signal to satellite radio receivers. The radio signal is broadcasted by communication satellites to a much larger area than traditional terrestrial radio antennas. For example, satellite radio is available al across the continental area of the United States. Satellite radio is available now in most parts of the world trough services provided by companies like WorldSpace (in Europe, Asia and Africa), Sirius and XM Radio (in North America). The radio signal you receive using satellite radio is digital, which means that it is always clear and static-free, which is one of the great advantages of satellite radio. Another great thing about satellite radio is that it is almost completely commercial-free.

To begin listening to satellite radio you will need the actual satellite radio (also known as tuner or receiver), a satellite radio antenna (which is often incorporated in the satellite radio) and a subscription to the service you choose. There are several types of satellite radio from which you can choose. One of them is the dedicated car or home radio, which play trough your car or home stereo. A second option is the plug-and-play radio, which can be used in your car, as well as in your home by paying a single subscription. Your third option is the portable radio, which has rechargeable battery, a built-in antenna and you can listen to it wherever you go using headphones. The radio signals offered by different satellite radio companies are proprietary, which means that you will need different hardware for receiving, decoding and playback, depending on your subscription. Each satellite radio receiver has its own serial number called Radio ID. When you get your subscription, you will also get an activation code for your receiver. Besides the actual radio programs, satellite radio transmits metadata that contains the name of the artist, the title of the song or program, as well as the name of the channel. This makes it easier for you to decide which channel to listen to and which program to choose.

Satellite radio services provide the subscriber with more than 100 programs that vary in content from rock and jazz to rap and classical music. But satellite radios utility reaches far beyond listening to your favorite music without the interruption of those annoying commercials. Satellite radio also offers exclusive sports programs, cultural and educational shows, news and talk-shows. Some of the celebrities that have moved their shows from free radio to satellite radio include Howard Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike terrestrial radio, satellite radio is not affected by bad weather or even calamities.

At first, many people wondered why they should pay for radio if they can get it free. However, satellite radio attracts more and more people every year due to its great advantages: no commercials, extensive reach, theme programs and exceptional quality of sound.
