HBO had gone to satellite transmissions to distribute its signal nationally in 1975, but that was a service that cable subscribers were made to pay extra to receive.

In 1979, the company changed its name to Turner Broadcasting System, Inc. (TBS, Inc.) and the call letters of its main entertainment channel to WTBS.

On March 4, 2019, AT&T would reorganize its broadcasting assets to effectively dissolve Turner Broadcasting System with its assets moving to the newly created WarnerMedia Entertainment with the unit consisting of HBO, TBS, TNT, TruTV, and an upcoming direct-to-consumer video service with Cartoon Network, Adult Swim, Boomerang, and Turner Classic Movies would be moved under Warner Bros. Entertainment via the new "Global Kids & Young Adults" business unit.

All linear networks owned by the company, besides CNN, Turner Sports, and HBO being overseen by Kathleen Finch as head of Warner Bros.
