Reruns of "Scooby-Doo" have been in syndication since 1980, and have also been shown on cable television networks such as TBS Superstation (until 1989) and USA Network (as part of the USA Cartoon Express from 1990 to 1994). In 1993, "A Pup Named Scooby-Doo", having just recently ended its network run on ABC, began reruns on the Cartoon Network. With Turner Broadcasting purchasing Hanna-Barbera in 1991, in 1994 the "Scooby-Doo" franchise became exclusive to the Turner networks: Cartoon Network, TBS Superstation, and TNT. Canadian network Teletoon began airing "Scooby-Doo, Where Are You!" in 1997, with the other "Scooby" series soon following. When TBS and TNT ended their broadcasts of H-B cartoons in 1998, "Scooby-Doo" became the exclusive property of both Cartoon Network and sister station Boomerang.
