These pages record some of the history of the early English-language sponsored or commercial stations that transmitted to the United Kingdom during the 1930s. In 1920, the first experimental broadcasts were transmitted by the Marconi Company. Thr first broadcast from 2LO from London was made on 11 May 1922 from a 100 watt trasmitter contained in a teak cabinet in Marconi House. Transmissions from 2LO were then limited to one hour a day.
