country's fourth national language, and the Zürich studios began broadcasting programmes in Romansh in between those in German. During the Second World War, SRG SSR filled an important function as a neutral, unbiased supplier of news, reaching far outside Switzerland's borders through shortwave transmissions. Radio Beromünster and Radio Monte Ceneri became known as the only free German and Italian-language radio stations in Europe. In 1950 SRG SSR was one of 23 founding broadcasting organisations of the European Broadcasting Union. In 1939 television test transmissions started in Zürich. In 1953 regular TV transmissions started in German (from Zürich) – one hour per evening, five days a week – immediately attracting 920 early TV licence buyers. A year later, in 1954, French transmissions were broadcast from Geneva. For the Italian-speaking region, the programmes were re-transmitted with Italian subtitles until dedicated Italian studios were built in 1958. 50,000 TV licences were bought the first year. In 1960 the company was renamed Schweizerische Radio- und Fernsehgesellschaft (and the equivalent names in the other languages - see above) to reflect the addition of television services. In 1964 the Federal Council allowed television advertising, as a means of keeping licence fees down. In 1966 the three main languages were each given a second radio channel, in order to counter the effects of new commercial broadcasters outside the country, whose strong signals were reaching the Swiss population. In the same year a dedicated Romansh broadcasting unit was created in Chur, using some of the new German-language second channel's broadcasting time. In 1968 colour television was introduced, and the number of licence fee payers passed one million. In 1978 the radio channels started stereo transmissions. In 1983 the Federal Council relaxed the Swiss media legislation to permit local private and commercial radio channels. SRG SSR countered this threat by launching its third set of channels, aimed at a younger audience. In 1991 SRG SSR underwent a wide-ranging restructuring. The enterprise organised itself as a private industry association, structured as a holding company under Swiss company law. The name, SRG SSR idée suisse, was introduced in 1999. In 1992 Radio Rumantsch was separated from the German-language radio broadcaster, that had housed the Romansh broadcasting activities since 1938, and in 1994 the Romansh TV activities were moved over as well and the Romansh company renamed itself Radio e Televisiun Rumantscha. In 1997, SRG SSR started digitally on Hot Bird (13
