“Fibber McGee and Molly” was a comedy series that aired on the NBC Red Network from 1935 to 1956.  Jim and Marian Jordan, a husband-and-wife team, created and portrayed the characters, which became some of the most popular in the history of radio.

Wikipedia sums up the plot:

Columbus’ Ohio State University launched experimental station 8XL in 1920.  In 1922, it became WEAO before adopting the WOSU call letters in 1933.

Over the decades, the station carried a wide variety of programs, featuring classical, jazz and opera.  WOSU became an NPR member station.  

The station’s classical music moved to WOSU-FM in 1980, which carried the music full-time as WOSU-AM carried more typical public radio programming.

In 2008, WOSU-FM added NPR news programming to its classical format, moving full-time classical music to it’s HD-2 radio service.  WOSU-AM continued with its NPR news/talk programming. 

In 2010, Ohio State purchased the license for 101.1 FM, which became WOSA-FM and carried the full-time classical format.  WOSU-FM switched to a full-time simulcast of WOSU-AM’s news/talk programming. 

The university sold WOSU-AM to St. Gabriel Radio in 2011.  It became WVSG-AM, airing Catholic religious programming.
