the Wall Street Journal from 2006[/url] talking about the Cardinals' move to KTRS. Selig isn't mentioned, but the purported demise of the 50 kW flagship and a subscription business model is discussed. But this was 4 years ago, and since then, the demise of the 50 kW flagship has been greatly exaggerated.
I don't think the driving factor is turning off the 50 kW signals to drive people to online/pay services. I think the driving factor is that teams like the Cardinals felt that they COULD sign up with a "lesser station", where they may not have thought so in the past, due to the alternatives (the Cardinals exec basically says that in the old article).
Of course, as mentioned, the Cardinals are heading back to KMOX. I think the business deal rules the day here, and not any purported desire by MLB/Selig to get off of 50 kW flamethrowers. My gut feeling is that the Cardinals lost more than just signal with KTRS, and CBS decided it wanted to get back in the baseball "game". (There's another "online truism" that says CBS wanted to back off on sports rights, remember?

)
So, I am not doubting you read something, but I think many others here did not, and are just repeating what you say because it fits in with their own take on the situation.
CBS O&Os don't have subchannels AFAIK, but I don't think they can dictate to affiliates what they can and cannot do. Many CBS affiliates use their subchannel(s) for multiple NCAA Tournament games in March, so that must bring in some extra revenue to the network and its affiliates.
You are correct, and CBS non-O&O affiliates in very big college basketball areas (NC/VA, etc.) have done this every year that I remember.
But there are folks going around saying that CBS has a "no subchannel mandate" that extends to their affiliate, and solely because the O&O's don't have subchannels. Perhaps CBS just hasn't come up with a business plan...perhaps they don't have subchannels not (as the "mandate" people say) because they want better HD quality. Perhaps they don't have subchannels because they don't have a business reason to do so, or haven't developed one yet (i.e. ABC's "Live Well", NBC's "Nonstop", etc.).
