The amount of commercials has nothing to do with Centric being a new network and needing ad revenue. Networks that air old shows do this a lot these days and I suspect it's just plain old greed, not need. I've noticed that the Viacom owned networks (Centric, Logo, BET, TV Land) are really bad about chopping out scenes in haphazard ways and inserting more commercials. And they all play the same commercials too!
I agree with you. It's not a "new channel thing." In fact, some channels when new play less commercials until they become bigger and greed takes over. (VH1 Classic and LMN come to mind--both had few ads when newer stations.) a new channel that plays a lot of ads seems to be fashioned after the networks owned by the company they're under that is guilty of doing it with all their stations.
"227" on VH1 right now is doing the same thing. Centric is terrible too, and I agree, it's a greed thing. Such a bummer to lose so much content for long ass commercial breaks.
