The 1920s was a decade of much change in communications. Apart from the introduction of sound broadcasting, the decade was noteworthy for the great expansion of long distance telephony in Europe, the engineering of the short-wave beam system, and the advancement of facsimile transmission. The 1924 concept of a national and a local radio service was later to be applied by the BBC to the post-war development of its television service.
