    NEW YORK, Aug. 19 /EMWNews/ -- SIRIUS XM Radio (Nasdaq:

2008 Democratic and Republican National Conventions.



    



    SIRIUS Convention Radio will offer listeners a unique opportunity to

"live" the convention experience. The channels will present live,

uninterrupted "gavel to gavel" coverage of every speech from the convention

podium, and replays of each day's highlights, as well as information on

convention agendas, schedules, events, and meetings.



    SIRIUS Convention Radio will also revisit key moments of convention

history with insight and reflections by members of both the Democratic and

Republican Convention committees, and SIRIUS hosts and former convention

participants Senator Bill Bradley and Ron Silver. In addition SIRIUS will

give voice to voters across the country with the People's Podium --

listeners will record their own brief political speeches to be broadcast on

the channel.



    SIRIUS Convention Radio En Espanol will provide real-time

Spanish-language translation of every speech, plus replays of each day's

events. The Spanish-language broadcast from the Democratic National

Convention will be provided by Comcast.



    "This marks a tremendous step forward to ensure all Americans can fully

participate in this year's historic Democratic National Convention and in

our democratic process," said 2008 Democratic National Convention Co-Chair

and Texas State Senator Leticia Van de Putte. "We applaud what SIRIUS is

doing to bring listeners across the country in to the Convention experience

and in particular its efforts to offer a bilingual simulcast for the more

than 35 million Americans who speak Spanish."



    Maria Cino, President and CEO of the 2008 Republican National

Convention, said, "We look forward to welcoming to St. Paul SIRIUS and the

hundreds of other media outlets that will help bring the 2008 Republican

National Convention into millions of homes across America and around the

world. It will be an historic event as Sen. John McCain accepts our party's

nomination and springboards into the general election."



    "SIRIUS will cover the Democratic and Republican National Conventions

like radio has never done before, with hosts from many perspectives, and

dedicated channels in both English and Spanish. We will use our technology

and extensive programming to give listeners unprecedented coverage of these

historic events," said Scott Greenstein, President and Chief Content

Officer, SIRIUS XM Radio.
