WPRB (103.3 FM) is a commercial broadcasting, non-profit 14,000 watt college radio station, once part of Princeton University, broadcasting from Princeton, New Jersey. The majority of on-air and management staff consists of Princeton University students, in addition to a board of trustees comprising Princeton University alumni. Its broadcast consists mostly of independent rock, classical, news, jazz, and world music; WPRB also provides coverage of many of Princeton University's varsity sporting events and is in the process of restarting its news department. One of its disc jockeys, Jon Solomon, has hosted a 24-hour Christmas music marathon every year but one since 1988.
WPRB was founded as WPRU in 1940 by H. Grant Theis, a Princeton University student at the time. It often is cited as the oldest commercially licensed campus radio station in the United States. WPRU became WPRB in 1955, and in that same year became an FM station, making it the first college FM station in the United States. WPRB was a pioneer in FM Stereo broadcasting, transmitting a stereo signal beginning in 1964. In 1986, Spin Magazine named WPRB the best commercial college station in the country.
After decades of operation under an advertising-supported business model, in 2006 WPRB switched to a listener-supported model (although it remains a commercially licensed station). This proved to be successful enough that in 2009 WPRB was able to acquire a Princeton student magazine, the Nassau Weekly. Nassau Weekly was founded in 1979 by Princeton students including David Remnick, who later became the editor of The New Yorker.
