WBGU's origins begin with a public address system built to broadcast a Bowling Green basketball game with audio phoned in from New York City in December 1947. This led to a carrier current station known as "WRSM" signing on in January 1948 at 600 kHz. This station, run by students and volunteers, was authorized by the Federal Communications Commission (FCC) and was affiliated with the Intercollegiate Broadcasting System. Repeated expansion led the university in 1951 to apply to the FCC for a construction permit to build an FM broadcasting station, licensed as "WBGU" in November 1951, with 10 watts of effective radiated power on a frequency of 88.1 MHz. In the six decades since it launched, the station has upgraded its signal strength, studio facilities, and equipment to meet the needs of the campus and the surrounding area.
WBGU is also the flagship home for Bowling Green hockey and Bowling Green women's basketball.
