Now that CBS is gone from radio, KTRH may never have CBS TOH news and/or be a CBS all-news station.
It depends on what CBS Radio will be. It has to be more than just owned and operated stations. Will they revive the CBS Radio Network? If they do, the network could go back to distributing CBS News Radio (rather than the current situation) and they might also distribute CBS Sports Radio.
As far as concentration of ownership, the media landscape is much bigger now than just AM, FM, and TV. Even though the FCC can't see this, the marketplace knows it is true. So media concentration isn't as big an issue as it was 20 years ago.
