The Susquehanna Pfaltzgraff Company was a conglomerate of companies that started in the 19th century with Johann George Pfaltzgraff's emigration from Germany to York, Pennsylvania (in the Susquehanna Valley).
Susquehanna Broadcasting Company was founded in 1941 to apply for and operate a radio station in York, Pennsylvania, by Louis J. Appell, president and treasurer of Pfaltzgraff. The Federal Communications Commission issued a construction permit for the station, which would become WSBA, on December 30, 1941.

- In 1993, Susquehanna Media Company (SMC) was formed, of which Susquehanna Communications was a subsidiary (but, as of 2007, is owned by Comcast).

Susquehanna Radio owned and operated 33 AM and FM stations nationwide at its peak, including WSBA AM in York, PA.
