In radio and television, broadcast delay is an intentional delay when broadcasting live material, technically referred to as a deferred live. Such a delay may be to prevent mistakes or unacceptable content from being broadcast. Longer delays lasting several hours can also be introduced so that the material is aired at a later scheduled time (such as the prime time hours, or in a different time zone) to maximize viewership. Tape delays lasting several hours can also be edited down to remove filler material or to trim a broadcast to the network's desired run time for a broadcast slot, but this is not always the case. This has often been used in Olympic Games coverage when the games were held in places where the time difference would not produce favorable viewership numbers in the country where the event is being broadcast. An example would be a delay of broadcasting the coverage of Dorothy Hamill winning the gold medal in women's figure skating at the 1976 Winter Olympics in Innsbruck, Austria, which is at UTC+1 during the winter and the Eastern time zone in North America is at UTC-5 (and the Pacific time zone at UTC-8, a six to none hour difference and having the event be an late morning/early afternoon broadcast in North America.
