Question about the new TV show, Life is wild?

I've seen commercials about that new show, "Life is Wild" (about the family that moves to Africa) on the television station, WPIX. I really wanna check it out. The only problem is, the television station it's supposed to be on is The CW, and I've never heard of it. I have no idea what channel that is. Does anyone know what that channel is? Or, will "Life is Wild" be on some other channel, like WPIX (the one it's being advertised on)? Anybody know????
