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.

"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.

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.
