broadcast: [18] Broadcast was originally an adjective and adverb, and meant literally ‘scattered widely’, particularly in the context of sowing seeds. A metaphorical sense developed in the late 18th and 19th centuries (William Stubbs, in his Constitutional History of England 1875 writes of ‘broadcast accusations’), and the word was ready in the early 1920s for application to the transmission of radio signals (the first actual record of such a use is as a verb, in the April 1921 issue of Discovery: ‘The [radio] station at Poldhu is used partly for broadcasting Press and other messages to ships’).
