2MT was the first British radio station to make regular entertainment broadcasts, and the "world's first regular wireless broadcast" for entertainment. Transmissions began on 14 February 1922 from an ex-Army hut next to the Marconi laboratories at Writtle, near Chelmsford in Essex. Initially the station only had 200 watts and transmitted on 700m (428 kHz) on Tuesdays from 20:00 to 20:30.
