What is Sirius Satellite Radio?
Sirius is radio the way it was meant to be: up to 100 new channels
of digital quality programming delivered to listeners coast to coast
via satellite. That means 60 channels of completely commercial-free
music. Plus up to 40 more channels of news, sports, and
entertainment from names like CNBC, Discovery, SCI-FI Channel,
A&E, House of Blues, NPR, Speedvision and Comedy World.
NOTE
When initially activating your subscription, if you have changed your
subscription, or if SIRIUS itself has updated streaming broadcast
service, automatic reselection of reception operates by following the
current channel setting.
At this time, audio reception may be momentarily interrupted.
However, this interruption is not caused by radio interference or
reception interference.
Sirius is live, dynamic entertainment, completely focused on
listeners. Every minute of every day of every week will be different.
All 60 commercial-free music channels are created in-house and
hosted by DJs who know and love the music. Do you like Reggae?
How about Classic Rock or New Rock? Sirius has an array of choices
spanning a vast range of musical tastes including the hits of the 50’s,
60’s, 70’s, & 80’s as well as Jazz, Country, Blues, Pop, Rap, R&B,
Bluegrass, Alternative, Classical, Heavy Metal, Dance and many
others…
From its state-of-the-art, digital broadcasting facility in Rockefeller
Center, New York City, Sirius will deliver the broadest, deepest mix
of radio entertainment from coast to coast.
Sirius will bring you music and entertainment programming that is
simply not available on traditional radio in any market across the
country. It’s radio like you’ve never heard before.
So Get Sirius and Listen Up! For more information, visit
<www.sirius.com>.
