They are major networks, or at least CW is. And I know CW is not part of the Big Four, but it's still a major network. And to some lesser extent, MyNetworkTV is too. Before I "moved" to the Twin Cities, Rochester, MN didn't carry either when I wasn't with Dish because the networks are on subchannels. But, my understanding is that if one of the Big Four is on a subchannel, they will carry that. I can understand networks like MeTV or THIS, but why these? They only carry it if it's on a primary.
