Rediffusion was a business that 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, the first ITV (commercial television) franchisee to go on air in the UK. Rediffusion also spawned a record label, Rediffusion International Music, in 1968 (which was also responsible for the short-lived Koala label).[1][2]
Redifon was the name used, until 1981, for companies in the capital goods businesses of Rediffusion, namely Redifon Computers, Redifon Flight Simulation and Redifon Telecommunications.
The Rediffusion brand has been revived and is currently used in China on consumer electrical products and on LED televisions in the UK.
