Prewar television stations

This is a list of pre-World War 2 television stations of the 1920s and 1930s. Most of these experimental stations were located in Europe (notably in the United Kingdom, France, Germany, Italy, Poland, The Netherlands, and Russia), Australia, Canada and the United States. Some present-day broadcasters trace their origins to these early stations.

All television licenses in the United States were officially "experimental" before July 1941, as the NTSC television standard had yet to be developed, and some American television broadcasters continued operating under experimental licenses as late as 1947, although by then they were using the same technical standards as their commercial brethren.
