LTV signed on the air on 20 November 1954. as the very first TV network in Latvia and the Baltic countries. Test transmissions began on 6 November 1954, just 14 days when it began regular broadcasts.

At the beginning, LTV did not have rights to create their own programming except live shows. In 1955, the Riga Television studio in Nometņu iela, Āgenskalns was created to produce its own programming and the first TV tower in Latvia was built.

On 19 March 1958, the first evening news show went on the air. In 1963, it was renamed Panorāma, as it is known to this day. A second TV channel was launched in 1961 and both channels converted to SÉCAM color in 1974. In 1986, both the Riga TV Tower and the LTV television headquarters in Zaķusala were officially completed.

The buildings in Zaķusala were one of the locations defended during The Barricades. During the 1991 Soviet coup d'état attempt troops of the OMON unit seized the LTV building on August 21, suspending broadcasts for two days.

On 2 February 1998, LTV1 converted to PAL color.

LTV1 changed its aspect ratio from 4:3 to 16:9 in 2013. Selected programming such as live broadcast of a staging of The Nutcracker by the Latvian National Opera on LTV1 in 2012, were shown in HD. In 2019 a full switch to HDTV broadcasts was announced for 2021 or 2022, although delayed in previous years due to financial constraints. After upgrading their broadcasting technology, both TV channels and content on the REplay.lv and LSM began a gradual switch to Full HD (1080p) on 19 May 2021 for cable and online broadcasts (the switch for free terrestrial operators is scheduled for 2022).
