There are a lot of major media companies that either own no radio, or have sold off radio stations. In just the last few years, those media companies include ABC/Disney, CBS, and Scripps. But Fox has never owned radio stations. Time Warner has never owned radio. Comcast has never owned radio. NBC sold off its radio in 1988. My point being that if any of those companies had bought Tribune, WGN would be for sale. Not because of some "curse," but because they simply don't own radio stations. Nexstar has never owned radio. Sinclair might have kept the station, since they own radio in Seattle. But its likely WGN-AM will be sold regardless of who is in the lineup, where the studio is located, and how expensive their staff is. It's a single station AM. Not part of a group. It's an orphan.
