The word 'sportscast' is a modern American English compound, formed in the early 20th century with the rise of radio. The first element, 'sports', is a truncation of 'disport', which entered English from Old French with the sense of 'pastime' or 'amusement'. The second element, 'cast', derives from Old Norse 'kasta', meaning 'to throw', which evolved in English to encompass the idea of projecting or transmitting something, as in 'broadcast'. Thus, a 'sportscast' literally means the act of 'throwing' or transmitting reports of games and athletic contests to a wide audience, perfectly capturing its function in media.
