TV's X Factor will this weekend mark the end of an era in popular entertainment with the final ever live broadcast from its London studio.
Fountain Studios in Wembley will shut its doors after Sunday's semi-final results show. The site is being redeveloped as housing.
TV shows were first transmitted from Wembley at the start of ITV in 1955 under the brand of Associated Redifussion and later London Weekend.
The studios were home to some of ITV's best loved programmes of the 1960s and 70s including period drama Upstairs Downstairs, sitcom On The Buses and pioneering pop show Read Steady Go.
Talents shows Pop Idol, X Factor and Britain's Got Talent continued the legacy, making stars of One Direction, Susan Boyle, Olly Murs and Will Young.
