Rediffusion was a business which distributed radio and TV signals through wired relay networks. The business gave rise to a number of other companies, including Associated-Rediffusion, later known as Rediffusion London, one of the first companies to win a terrestrial ITV (commercial television) franchise in the UK. Rediffusion also spawned a record label, Rediffusion International Music, in 1968. Redifon was the name used until 1981 for companies in the capital goods businesses of Rediffusion, viz. Redifon Computers, Redifon Flight Simulation and Redifon Telecommunications.
Rediffusion was the trading name of Broadcast Relay Service Ltd, formed in 1928. In 1929 the company introduced its first cable radio service in Hull to customers frustrated with the difficulties of tuning in weak radio broadcasts. Initially, the service consisted primarily of rebroadcasts of the BBC Radio service, which was reflected in the trading name: Rediffusion simply means "broadcasting again".
Rediffusion quickly branched out into making, renting, and selling radios, both receivers for its cable services and conventional models. With the arrival of the first experimental television broadcasts in the 1930s, Rediffusion began manufacturing TV sets and supplying "Piped TV", an early form of cable TV, service to its customers, until the cessation of television broadcasts during the Second World War.
The first British colony to have the Rediffusion service was Barbados in 1934, when Radio Distribution (Barbados) Limited was formed.
A year later, Rediffusion started operating in Malta. Transmissions in Malta started from Hamrun on 11 November 1935 under the name of "Broadcast Relay Service Malta Ltd." Mr. Charles Whotcroft and Mr. George Powler were the first manager and chief engineer respectively.
In 1947 British Electric Traction acquired a substantial minority interest in Rediffusion. BET acquired a controlling interest in 1967, and the remaining 36% of equity in 1983.
