ČT1

The channel was launched by Czechoslovak Radio on 1 April 1953; control of which was handed over to Czechoslovak Television in 1957. At the time, all of its programming was conducted on the same national transmitter network, covering the entirety of Czechoslovakia. In April 1969, the Federal Minister of Posts and Telecommunications suggested a second channel, which started broadcasting on 10 April 1970. The existing channel, becoming the First Programme (I. program) was conceived as a mainstream network. This channel started colour broadcasts on 9 April 1975, two years after the second channel. The channel's coverage at the time was of 94,5 % of Czechoslovakia, slightly increasing to 95% in 1980.

After the Velvet Revolution, the original I. program was replaced by F1 on 2 September 1990.

On 1 January 1993, F1 changed its name to ČT1 in Czech Republic and STV1 in Slovak Republic. The channel subsequently became the first channel of the new Czech Television, created one year earlier following the Velvet Revolution. Since September 1997, the station has been broadcasting 24 hours a day.

Analogue broadcasting of ČT1 ended on 30 November 2011. The broadcasting of multiplex 1 (DVB-T standard) was announced in November 2019 and ended on 30 September 2020.

Until February 2013, ČT1 HD broadcasts could also be received via Multiplex 4 of Digital Broadcasting s.r.o. However, this test broadcast was terminated.
