 Following World War II the BBC reorganized its radio provision, introducing two new channels to supplement the BBC Home Service (itself the result of the fusion in September 1939 of the pre-war National and regional Programmes).These were the "BBC Light Programme" (dating from 29 July 1945 and a direct successor to the wartime" General Forces Programme") and the" BBC Third Programme "(launched on 29 September 1946).The "BBC Light Programme", while principally devoted to light entertainment and music, carried a fair share of drama, both single plays (generally, as the name of the station indicated, of a lighter nature) and serials.
