During The Killer Bee era, the station competed strongly with WMEE for all hit music listeners in Fort Wayne.
"Sunny" was a ratings success, and featured a local morning show hosted by Fort Wayne radio mainstay Ron Gregory.
In 2003, however, owner Shine Broadcasting Services, LLC, announced it was looking to sell WSHI, and in January 2004, dropped the standards format in favor of mainstream adult contemporary.
In January 2007, Artistic Media Partners, Inc. agreed to sell WSHY and sister station WBTU (93.3 FM) to entrepreneur Russ Oasis, for $3.8 million.
The following month, Oasis flipped the station to a gold-based Rhythmic Adult Contemporary format, branded as "Vibe 106.3", with an emphasis on Disco and Classic Dance from the 1970s, 1980s and 1990s.
On September 27, 2008, Russ Oasis' Radio Group dropped the Rhythmic AC format in favor of Variety Hits as "106.3 Joe FM".
On April 3, 2013, at 6:00 PM, the station dropped the Rhythmic format ("Clickhop.com" continues on their website and mobile applications, though this was later discontinued), and flipped to 90's Hits, branded as "Rewind 106.3."
