Launched on 1 May 1954 to succeed
Télé Genève, RTS Un is the first channel of the two Swiss French networks of television group RTS (the other being
RTS Deux). The channel first aired programmes in colour in 1968. RTS took part in the creation of
TV5 in 1984, and provides programmes for the international channel. In 1990 Andrea Marconi created the brand identity with the new logo of the humanized profile of the then TSR. Following the launch of TSR 2 in 1997, TSR renamed itself TSR 1 and RTS Un in 2012. RTS Un is available in
Aosta Valley, Italy, due to Italian self-government laws, and until the cessation of all digital terrestrial signals in Switzerland in 2019 could also be received in the border areas via spillover. ==Logos and identities==
