WGTB (often referred to as GTB) is Georgetown's college radio station. The original WGTB callsign was held by Georgetown University from 1946 until 1980. During the 1970s the station was plagued by financial issues and controversies surrounding its programming, resulting in the University's decision to shut it down in 1978. In 1980, the WGTB license was donated to the University of the District of Columbia, who sold it to CSPAN in 1997 for $25 million.
