Thomson, now called Technicolor SA, also owns the RCA brand and licenses it to other companies Radio Corporation of America, the originator of that brand, created the NTSC colour TV standard before Thomson became involved.The term PAL was often used informally and somewhat imprecisely to refer to the 625-line/50 Hz (576i) television system in general, to differentiate from the 525-line/60 Hz (480i) system generally used with NTSC. Thomson also bought the Compagnie Générale de Télévision where Henri de France developed SECAM, the first European Standard for colour television. It was followed by Loewe-Farbfernseher S 920 & F 900.Telefunken was later bought by the French electronics manufacturer Thomson. Telefunken PALcolor 708T was the first PAL commercial TV set. The one BBC channel initially using the broadcast standard was BBC2, which had been the first UK TV service to introduce '625-lines' in 1964. The first broadcasts began in the United Kingdom in June 1967, followed by West Germany late that year. When asked, why the system was named 'PAL' and not 'Bruch' the inventor answered that a 'Bruch system' would probably not have sold very well ('Bruch' lit. The format was patented by Telefunken in 1962, citing Bruch as inventor, and unveiled to members of the European Broadcasting Union (EBU) on 3 January 1963. The goal was to provide a colour TV standard for the European picture frequency of 50 fields per second (50 hertz), and finding a way to eliminate the problems with NTSC.PAL was developed by Walter Bruch at Telefunken in Hanover, West Germany, with important input from Dr. To overcome NTSC's shortcomings, alternative standards were devised, resulting in the development of the PAL and SECAM standards.
