The FCC-licensed FM station first went on the air in June 1958, though the WVBR call letters had already been in use for years on the Guild's AM "carrier-current" broadcasts, which could be received only on campus. The call letters originally stood for "Voice of the Big Red", referring to the Cornell Big Red athletic teams. But the station de-emphasized that connection over the years as it carved out an identity independent of the university, and as the university's sports broadcasts were generally carried by WHCU, a commercial station that Cornell owned for many years. (This has changed to a degree in recent years as WVBR has become the originating station for sponsored broadcasts of some major Cornell sports, including football, basketball and hockey.) (At least in the early 70s, WVBR was said to stand for "Very Bad Radio.")
