Primetime is an American news magazine television program that debuted on ABC in 1989 with co-hosts Sam Donaldson and Diane Sawyer and originally had the title Primetime Live. The program's final episode aired May 18, 2012. Originally, the program aired live on the ABC network and featured a live studio audience. The first interviews included Roseanne Barr and a piece on a Middle East hostage crisis reported by Chris Wallace. Donaldson and Sawyer would allow audience members to comment on the program and ask questions of the guests, who were usually interviewed live via satellite or in studio, a practice that resulted in many technical difficulties and easy satirization on Saturday Night Live. Internal conflicts between Sawyer and Donaldson later led them to be separated, and the audience eliminated. However, the program has always had some live elements when broadcast as Primetime Live, generally consisting of Donaldson reading the opening remarks of packaged stories and the opening title as Primetime... LIVE!. Over time, live interviews were de-emphasized and hidden camera investigations began to occupy more of the schedule.
