From the New York Times:

Like Oprah Winfrey and Ryan Seacrest before him, the music mogul Sean Combs wants a spot on the cable channel lineup.

Mr. Combs will unveil on Tuesday his plans for a music-oriented cable channel called Revolt, a public relations agency managing the announcement said Monday. The channel may start by the end of the year.

Mr. Combs will bill Revolt as a music and news television channel influenced by the nonstop chatter of social networking Web sites. It is the latest of several challenges to MTV and BET, both owned by Viacom.

More after the jump.

Comcast, the nation’s largest cable television provider, will carry Revolt on some of its local cable systems, although the total number of homes is unclear. Comcast declined to comment Monday.

When it was lobbying the government to approve its proposed acquisition of a majority stake in NBCUniversal, Comcast pledged to carry several new channels owned by minorities. The channel from Mr. Combs, who is African-American, was one of the pitches Comcast picked last year.

Time Warner Cable, the nation’s second-largest cable provider, has also held discussions about carrying Revolt. Maureen Huff, a spokeswoman, said Monday that the talks were continuing.

Mr. Combs’s plans for Revolt were first reported by Broadcasting & Cable magazine last month. When interviewed by a reporter for MTV recently, Mr. Combs said little about the proposed channel, except that “we’re coming with a new energy, we’re coming with something that people are going to want to tune in to see.” Mr. Combs, also known as Diddy or P. Diddy, praised MTV and BET for “paving the way” and making him a global star.

Best known for his rap hits, Mr. Combs, the chief executive of Bad Boy Entertainment, has also produced hit cable television shows, including “Making the Band” for MTV.

It is unclear how big an on-camera role he would have on Revolt. Ms. Winfrey, who partly owns the year-old channel OWN, appears on it regularly. Mr. Seacrest, who recently became a stakeholder in AXS TV, a channel that will replace HDNet this summer, will not be the face of that channel. But the arrangements show the interest among A-list celebrities in planting a flag in cable television.
