Rap mogul Sean "Diddy" Combs is launching his own cable network.

The "I'll Be Missing You" hitmaker has teamed up with executives at Comcast to create new music channel Revolt TV.

Announcing the news during a personalised YouTube.com video on Tuesday, he said, "When I was growing up I used to watch television all the time and I used to wonder why don't those people look like me, or talk like me, or walk like me, so thank you to Comcast - my hat goes off to you for being the first to step up... because Revolt TV is bringing the revolution that TV needs..."

"I had a dream that one day I would get a chance and opportunity to show my perspective coming from a musical standpoint. I take a lot of pride in having experience, credibility, authenticity and the relationships to make Revolt TV the number one name and home for music on television. I'm gonna give the artists this channel... A channel that will give new artists an opportunity to get seen and to get heard (sic)... This network will represent the soul of music that's been missing for a long time. I got a lot of work to do, it's gonna be a marathon not a sprint but I will not stop until we on top (sic)."

Revolt is slated for a 2013 launch.

Comcast chiefs have also inked deals with basketball legend Earvin 'Magic' Johnson and Hollywood director Robert Rodriguez to create their own TV networks.

Retired Johnson will launch 24-hour black network Aspire in June and filmmaker Rodriguez will premiere El Rey, an English-language channel aimed at Latino audiences, in 2014.

All three business ventures reflect a recent Comcast Corp. agreement with the Federal Communications Commission (FCC), in which the cable operator's executives vowed to diversify their line-up with the launch of 10 new networks by 2018.
