The initial broadcasting station at the University of Illinois, WILL (originally WRM), was first licensed as an AM station in 1922. An FM station, WILL-FM (originally WIUC), was introduced in 1942, and a TV station, WILL-TV debuted in 1955. From 1942 to 1998, these station's studios were located at university's Gregory Hall. After World War II, the university hosted the National Association of Educational Broadcasters (NAEB) for the establishment of broadcast allocations (AM/FM radio and TV channels) for non-commercial education programming. The NAEB was based at Gregory Hall from 1951 to 1961.
