In October 25, 1965, after his exit from Four Star Television as a staff writer prior to becoming a producer, Aaron Spelling formed his own company with Danny Thomas, Thomas-Spelling Productions.
Thomas-Spelling Productions was a television production company formed by comedian Danny Thomas and producer Aaron Spelling on April 15, 1966 as a partnership with 24 properties. The company adapted its name by July 18, 1966 when it announced the financial involvement of ABC with its first show, Range (later Rango), a half-hour comedy western starring Tim Conway. ABC also pick up another show for a pilot, just in an outline treatment, in The Guns of Will Sonnett. Thomas-Spelling Productions' active operations ended with the last season of The Mod Squad in 1972. Spelling formed a new partnership with Leonard Goldberg, Spelling-Goldberg Productions
In the late 1970s/early 1980s, Spelling was called king in television. In 1982, Aaron Spelling Productions struck a deal with Warner Bros. Television Distribution for worldwide syndication rights to future Spelling productions. In 1984, Spelling had seven shows for the ABC television network, accounting for one-third their prime time schedule. This outweighed other production companies by a large margin, leading many industry insiders to dub ABC as "Aaron's Broadcasting Company". Spelling himself was never amused with this name.
Aaron Spelling Productions went public in 1986 after raising $80 million. On August 17, 1987, Spelling extended its contract with ABC for three more years. On September 28, 1987, Spelling's arrangement with ABC became non-exclusive as it was signed a deal to other networks. In 1988, Aaron Spelling Productions acquired Laurel Entertainment and most of the Taft Entertainment Company, including Worldvision Enterprises, Inc. All three companies became part of Spelling Entertainment Inc. – though Worldvision was the only Taft division to continue operating. The sale was completed on March 1, 1989.
