SRG SSR
Switzerland introduced DTT in 2007. Switzerland later become the first country to eliminate broadcast terrestrial television entirely when public broadcaster SRG SSR, which runs the country's only terrestrial channels, shut down its DVB-T transmitter network in June 2019. SRG SSR estimated that less than two per cent of households relied on its DVB-T network, the large majority of which used it only for reception on secondary devices, making continued operation not economically viable. Its programing will remain on IPTV services, cable, and free-to-air satellite. SRG SSR recommended consumers to switch to satellite. As the satellite signals are free but encrypted to restrict reception to Swiss residents, there is now one privately owned DVB-T transmitter on Hoher Kasten in Appenzell to feed the channels of SRF to cable systems in Vorarlberg, Austria.
