WOSU (820 AM) was a National Public Radio news and talk radio station located in Columbus, Ohio serving the Columbus metro area. WOSU is licensed by the Federal Communications Commission as a daytime and nighttime radio station, operating with a non-directional power of 5 kW during the day, and dropping to 790 watts at night, to protect clear channel WBAP in Fort Worth, Texas. The license holder was The Ohio State University until the license changed hands over to St. Gabriel Radio Inc. It is now WVSG.
WOSU is the oldest radio station in Columbus. WOSU's origins trace back to 1920 when Ohio State University was granted an experimental license on April 20, 1920. On June 3, 1922, the station received the call letters WEAO (Willing Energetic Athletic Ohio). In 1933, the call letters were changed to WOSU.
For much of the 1960s and '70s, WOSU's programming was mostly locally originating featuring diverse music programs from classical and jazz...and later to the seasonal Metropolitan Opera radio broadcasts on Saturday afternoons moderated by its long-time announcer Milton Cross and later by Peter Allen after Cross' passing leading to the gradual evolution of National Public Radio and its WOSU affiliation. WOSU also broadcast live remotes from the Ohio State Fair.
