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 February 14, 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 2000 to 2030.
2MT led to the creation of its sister station 2LO, and subsequently the BBC. 2MT did not itself become part of the BBC and closed down on January 17, 1923.
