Associated-Rediffusion
British ITV contractor for London and parts of the surrounding counties

Associated-Rediffusion, later Rediffusion London, was the British ITV franchise holder for London and parts of the surrounding counties, on weekdays between 22 September 1955 and 29 July 1968. It was the first ITA franchisee to go on air, and one of the "Big Four" companies that between them produced the majority of ITV networked programmes during this period.
Rediffusion lost its franchise in 1968 but merged with another franchisee to form Thames Television, which continued to hold the London weekday franchise for another 24 years.
History
Formation
Associated-Rediffusion Television was originally a partnership between British Electric Traction (BET), its subsidiary Broadcast Relay Services Ltd. (trading as Rediffusion), and Associated Newspapers, owner of the Daily Mail, which had been interested in commercial broadcasting as early as the 1920s. In the aftermath of the heavy financial losses made by the new ITV system in its initial years, Associated Newspapers sold the majority of its share to BET and Rediffusion, although the company did not drop the word "Associated" from its name until 1964. Associated Newspapers, later realising the potential of ITV, was a significant investor in the ITV franchise contractor for southern and south-east England, Southern Television and, much later, became a shareholder in Westcountry Television and Independent Television News.
Thomas Brownrigg, the general manager of Associated-Rediffusion from 1955, had a very clear idea of what his new commercial television station was to be like – the BBC Television Service, with advertisements. To this end, the station had a heraldic-style on-air clock, referred to as "Mitch" by staff (after chief station announcer Leslie Mitchell, who had not only made the first announcement when A-R went on the air in 1955, but had done the same when the BBC TV service started in 1936).
Associated-Rediffusion took over the former Wembley Film Studio at Wembley Park in Middlesex.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
