Radio in Latvia began with an evening voice from the Main Post Office building. On 1 November 1925, Rīga Radiofons was officially opened: first came an address by Minister of Transport Jānis Pauļuks and the national anthem, then a connection to the National Opera for Puccini’s Madama Butterfly. The first broadcast had only two hours on air and 331 subscribers—a small circle of listeners at the moment when a public age of sound was born in Latvia.

In interwar Latvia, radio quickly became a carrier of news, music, and the presence of the state beyond the capital. Rīga Radiofons at first broadcast for only a few hours a day, but by the 1930s radio could be heard across the entire country.
