At 5 p.m. PST Monday, the all-music channel goes live in the homes of  about 22 million Comcast subscribers and 12 million Time Warner Cable  customers, marking one of the biggest launches of a cable channel in  years.

Revolt TV is the latest brainchild of Combs (aka Diddy, P. Diddy,  Puff Daddy), a serial entrepreneur who has found success in music as an  executive and hip-hop artist as well as in fashion, liquor, marketing  and more, helping him accumulate a fortune that Forbes estimated in 2012  at $550 million.

Now, seven years after he first conceived of a new kind of all-music  channel, Combs is pouring tens of millions of that into launching a  service aimed at 18- to 34-year-olds -- members of the millennial  generation -- who consume more music than ever but not necessarily in  the traditional ways of listening to the radio or watching cable TV. In  fact, they are the generation often described as "cord cutters," because  they haven't rushed to subscribe to cable and often are more likely to  view TV on a mobile phone or tablet computer than on the living-room  flat screen.
