RTS Un is a Swiss public television channel owned by Radio Télévision Suisse, the public broadcaster for the French speaking Switzerland.


Launched on 1 November 1954 to succeed Télé Geneva, RTS Un is the first channel of the two Swiss French networks of television group RTS (the other being RTS Deux). In 1968 the channel first aired programmes in colour.

RTS took part in the creation of TV5 in 1984, and provides programmes for the international channel.

Following the launch of TSR 2 in 1997, TSR renamed itself to TSR 1 and RTS Un in 2012.

RTS Un is available in Aosta Valley, Italy, due to Italian self-government laws, and in the border zones because of natural spillover.
