It's odd that they don't name the channel. I can't imagine they haven't picked it yet. Chances are, it's Comedy Gold. A retro channel mixed in with Bell's suite of channels is an odd man out, retro TV isn't 'sexy', and it's one of only two channels that Bell owns 100% of that's a category B, the other being Investigation Discovery, which I think is definitely a bigger priority than Comedy Gold.
But either way, since Bell is going to own a stake in WOW, is it really much of a sell off? Chances are, as WOW grows, Bell will likely end up buying it outright down the road anyways. This sounds like nothing more than a test run.
