2LO was the second radio station to regularly broadcast in the United Kingdom. It began broadcasting on 11 May 1922, for one hour a day from the seventh floor of Marconi House in London's Strand, opposite Somerset House.

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.
