The station went on the air in on December 13, 1962 as WNEU, broadcasting only to a few dorms on campus. In 1970, the station then changed to call letters WRBB and began broadcasting on 91.7 MHz. In 1982 the frequency changed to the current 104.9, due to interference from other stations and FCC rulings. Despite its signal coverage within Boston, its 104.9 frequency collides with nearby WBOQ, which covers the North shore area.
In addition to variety of music played, all major Northeastern basketball, baseball and hockey games are also broadcast live on WRBB. It was one of the first college radio stations in the country to broadcast hip-hop music during the early 1980s.
