The Marconigraph is a British monthly technical science magazine focused on radio, which began in April 1911 as a mouthpiece for the Marconi Company (in 1925 the magazine disassociated from the Marconi Company to become an independent publication). In April 1913 it was renamed The Wireless World. In April 1922 it absorbed The Radio Review, and was renamed The Wireless World and Radio Review. It is still in publication, but under the new banner of Electronics World.
Note that for a brief period, from October 1912 to September 1913, The Marconigraph was also published in a different edition specifically for the American market.
