The History of Radio Times magazine began in 1923 when the BBC's first director general John Reith conceived of publishing a magazine dedicated solely to radio listings. Originally a joint project between the BBC and George Newnes Ltd, the BBC took over editorial control by 1925 and fully ran it in-house by 1937. Radio Times grew popular as one of the leading magazines of its time featuring prominent writers and illustrators. It became the world's first television listings magazine in 1936. Modern printing methods in the 1980s allowed for more color in Radio Times, and its popularity increased when the 1988 Christmas edition broke the British magazine record as the biggest selling issue ever.
