ABC Television was a production company involved in British comedy, founded in 1956 and closed in 1968.
One of the original ITV regional broadcasters, ABC was founded by the people behind the cinema chain of the same name.
After bidding for the London weekend broadcast licence in 1968, they were awarded the London weekday licence upon the condition that they merged with Rediffusion London, the then holder of the slot. The merger was agreed, and the two became Thames Television.
Thames lost its licence in 1992 and later merged with TalkBack Productions to become TalkbackThames, which still exists as an independent production company.
