WJY was a temporary longwave radio station, located in Hoboken, New Jersey and operated by the Radio Corporation of America (RCA), which was used on July 2, 1921, for a ringside broadcast of the Dempsey-Carpentier heavyweight boxing match.
The fight details were also telegraphed to station KDKA in East Pittsburgh, Pennsylvania, and broadcast from there by a local announcer. These broadcasts were a cooperative effort, designed to raise money for the American Committee for Devastated France and the Navy Club. This also marked RCA's entrance into the radio broadcasting field, which the company would dominate in the U.S. for the next half century.
