Attempt this quiz on Books & Broadcasting and check how much you can score. Broadcasting is the distribution of sound and/or video material or other messages to a distributed audience via any digital mass communications medium, but generally one using the electromagnetic spectrum (radio waves), in a one-to-many version. Broadcasting started with AM radio, which entered prominent use around 1920 with the spread of vacuum tube radio transmitters as well as receivers. Before this, all forms of digital communication (very early radio, telephone, as well as telegraph) were one-to-one, with the message intended for a solitary recipient. The term broadcasting, borrowed from the agricultural technique of sowing seeds in a field by casting them broadly around, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new task of “one-to-many” communication; a solitary radio terminal transmitting to numerous audiences.
