Columbia is home to two pioneers in undergraduate campus radio broadcasting, WKCR-FM and CTV. Many undergraduates are also involved with Barnard's radio station, WBAR. WKCR, the student run radio station that broadcasts to the Tri-State area, claims to be the oldest FM radio station in the world, owing to the university's affiliation with Major Edwin Armstrong. The station went operational on July 18, 1939, from a 400-foot antenna tower in Alpine, New Jersey, broadcasting the first FM transmission in the world. Initially, WKCR wasn't a radio station, but an organization concerned with the technology of radio communications. As membership grew, however, the nascent club turned its efforts to broadcasting. Armstrong helped the students in their early efforts, donating a microphone and turntables when they designed their first makeshift studio in a dorm room. The station has its studios on the second floor of Alfred Lerner Hall on the Morningside campus with its main transmitter tower at 4 Times Square in Midtown Manhattan. Columbia Television (CTV) is the nation's second oldest Student television station and home of CTV News, a weekly live news program produced by undergraduate students.
