The "TV Powww" format, produced and distributed by Florida syndicator Marvin Kempner, debuted in 1978 on Los Angeles station KABC-TV as part of "A.M. Los Angeles", and by the start of the next decade was seen on 79 local television stations (including national superstation WGN as part of "Bozo's Circus") in the United States, as well as several foreign broadcasters. While most stations had dropped "TV Powww" by the mid-1980s, stations in Australia and Italy were still using it as late as 1990.
