Accelerates Launch of Southeast to October; Will Cover Nation in November

XM Satellite Radio
today officially launched the first U.S. digital satellite radio service —
“Radio to the Power of X” — featuring 100 coast-to-coast, digital channels of
music and information.

“What we are doing is launching a powerful new communications and
entertainment medium — what we call ‘Radio to the Power of X,”’ XM President
and CEO Hugh Panero told a crowd of journalists, guests and XM staff gathered
at the company’s headquarters and 80-studio digital broadcast complex in
Northeast Washington.
“We have music channels to soothe your mind and
information channels to fill it.”
The event featured a videolink to XM’s lead
markets in Dallas and San Diego, where customers at retail stores were buying
some of the first XM radios.

XM’s programming lineup features 71 music channels, more than 30 of them
commercial-free; and 29 channels of sports, talk, children’s and entertainment
including 13 premiere news channels covering the latest national, world and
financial developments like CNBC, CNN Headline News, CNNfn, FOX News, ABC News
& Talk, USA Today, Bloomberg, BBC World Service, C-SPAN and its own XM News.
People for the first time will be able to receive on the radio the diverse
selection of 24-hour news sources that they’re used to getting at home on
cable and DirecTV.

As the digital countdown clock in XM’s high-tech glass and chrome
broadcast operations center hit zero, Panero pressed a button on the Star
Trek-like command chair, launching XM’s service.
He then videolinked to

XM Offers an Array of Music and News Channels Unprecedented on Radio

XM extends the reach of America’s most trusted and popular news and

On the music end, Panero said, “XM is Mozart and Metallica — Isaac Stern
and Isaac Hayes — Frank Sinatra and Frank Zappa — Bob Marley and Bob Dylan
— Louis Armstrong and Lou Reed.
XM is God Bless America.
XM is Quincy Jones
and Wynton Marsalis, who are part the XM ‘Artists Family’ and will create
programming for us. We are about every artist, across every genre.”

There has always been a unique relationship between technology, innovation
and the distribution of music, news and information, Panero noted.
45s, remember vinyl record albums, remember the introduction of FM radio, the
cassette, the Sony Walkman, the compact disc and cable TV with MTV?
They all
had dramatic impacts on music, bringing it to larger audiences in new and
different ways. Remember when there were only three broadcast television
networks? Soon people will say, ‘Remember when there was only AM and FM?’ And
that leads us to XM Satellite Radio.”

XM will transform radio, an industry that has seen little technological
change since FM, almost 40 years ago.

digital-quality, coast-to-coast sound for $9.99 a month.
