Planned Music Limited was established in March 1959 by Associated Television Limited as the British franchise owner of the Muzak System. It would begin operating in September 1959 using a distribution licence issued by the General Post Office (GPO). Initially, this was only available in London but it was later expanded into the Midlands and North West. Despite the initial success it suffered from higher-than-anticipated expenditure and delays in receiving GPO approval. It would eventually enter liquidation in 1998 and was dissolved in June 2001.
