Warner Bros. Television Studios (operating under the name Warner Bros. Television (abbreviated as WBTV); formerly known as Warner Bros. Television Division) is an American television production and distribution studio of the Warner Bros. Television Group division of Warner Bros. (both ultimately owned by Warner Bros. Discovery). Alongside Paramount Global's television arm CBS Studios, it serves as a television production arm of The CW (in which Warner Bros. Discovery has a 12.5% ownership stake), DC Comics and distribution arm of HBO, Cartoon Network and Adult Swim, it also has produced shows for other networks, such as Blindspot on NBC, Person of Interest and East New York on CBS, and Abbott Elementary on ABC, as well as produced shows for other streaming services such as Netflix and Amazon Prime Video such as The Sandman, Lucifer, and The Peripheral.

One such segment for Rebel Without a Cause featured Gig Young notably talking about road safety with James Dean. With only Cheyenne being a success, WB ended the ten-minute promotions of new films and replaced Warner Bros. Presents with an anthology series titled Conflict. It was felt that "Conflict" was what the previous series lacked. Conflict showed the pilots for Maverick and 77 Sunset Strip .
