Tyne Tees launched on 15 January 1959 from studios at a converted warehouse in City Road, Newcastle upon Tyne, remaining in the city until July 2005 when Tyne Tees moved to smaller studios in Gateshead. Tyne Tees has contributed various programming to the ITV network and Channel 4, as well as its regional output. Some of Tyne Tees' best known programming includes the groundbreaking music show The Tube, critically acclaimed adaptations of Catherine Cookson novels, and children's programmes such as Supergran. The ownership and management structure of Tyne Tees has altered across its history, particularly in various mergers with Yorkshire Television. The two stations were managed by Trident Television during the 1970s, and the two stations merged again in 1992 to form Yorkshire-Tyne Tees Television. A series of takeovers and mergers across the ITV network, instigated by the large groups Granada and Carlton, led to Tyne Tees becoming part of ITV plc in 2004.
