NY Times/Bill Carter January 22, 2013 Comedy Central is expanding to radio, having concluded a deal with Sirius XM Radio to create a new channel revolving around stand-up comedy and relying on material produced by the comedy cable network. In an arrangement announced Tuesday, Comedy Central will start up the channel on Sirius sometime this spring, perhaps as soon as the week that includes April 1â€”which would have the added value of being April Foolâ€™s Day. Comedy Central plans to mix new performances from comics with selections from its deep library of performances that have appeared on its television channel â€” from series like â€œPremium Blendâ€ and â€œComedy Central Presents,â€ as well as some of its roasts of celebrities. The channel also plans to visit comedy clubs and initiate programs hosted by comics. The channel also plans to visit comedy clubs and initiate programs hosted by comics.
