ABC owns nearly all its in-house television and theatrical productions made from the 1970s onward, with the exception of certain co-productions with producers (for example, The Commish is now owned by the estate of its producer, Stephen Cannell).
When the FCC imposed its fin-syn rules in 1970, ABC proactively created two companies: Worldvision Enterprises as a syndication distributor, and ABC Circle Films as a production company.
