Trident Television

Background
Trident Television was a British television company that was the owner of two ITV franchisees Yorkshire Television and Tyne Tees Television from 1970 to 1982, when the IBA forced to divest the franchisees during the 1980 renewal. It also considered purchasing Anglia, but it failed, and chose to make the non-television interests as the third prong of the company. It even started Trident Television Associates in 1979 to syndicate 23 CBS telemovies and a film subsidiary.
