TNT Sports Could Move to Free CBS over-the-Air TV
Following the completion of the Paramount-Warner Bros. Discovery merger, forming Skydance, CBS is poised to potentially redistribute TNT Sports programming to its free over-the-air network. CBS Sports president David Berson will lead the combined sports group after TNT Sports chief Luis Silberwasser's departure. Industry speculation centers on shifting high-value events like the Stanley Cup Final and other TNT/TBS properties to CBS to increase reach, as NHL commissioner Gary Bettman advocated. However, pre-merger carriage agreements with distributors like Comcast, DirecTV, and YouTube TV may complicate moves due to exclusivity-based fees. No immediate changes are planned, but the merger positions CBS to broaden free access to premium sports for antenna-only viewers.
- The $110 billion Paramount-Warner Bros. Discovery merger closed on October 6, 2026, creating Skydance.
- CBS Sports president David Berson will lead the combined global sports group.
- TNT holds rights to the Stanley Cup Final, which may move to CBS.
