102.1 FM was known as WSEV-FM (co-owned with WSEV-AM 930 in Sevierville) in its early years and was automated. On December 2, 1987, the station started playing a mix of adult contemporary and country music as "U-102". Eventually, the station started playing adult contemporary exclusively.
On May 20, 1994, the station switched call letters to WMYU as Oldies 102. On that same date, sister station 93.1 FM changed to Star 93.1 FM with the call sign "WWST". On March 9, 2001, the two stations swapped frequencies moving the WWST call letters to 102.1 FM as Star 102.1 while the "WMYU" call letters were moved to 93.1 FM where they remained until late 2008.
Journal Communications and The E.W. Scripps Company announced on July 30, 2014 that the two companies would merge to create a new broadcast company under the E.W. Scripps Company name that will own the two companies' broadcast properties, including WWST. The transaction is slated to be completed in 2015, pending shareholder and regulatory approvals.
