On September 2, 2006, Radio One, Inc. acquired the intellectual property and call letters of WMOJ-FM from Cumulus Media Partners, and moved it from 94.9 FM to 100.3 FM. 100.3 had been moved into the Cincinnati market by Radio One, after it purchased the former WIFE-FM in Connersville, Indiana.
Cumulus retained ownership of the 94.9 FM frequency, and after the 2006 Cincinnati radio station reorganization in which the 94.9 frequency was traded to Entercom Communications, 94.9 FM is now the home of WREW "Rewind 94.9", an adult hits station. The station is now operated by Hubbard Broadcasting.
While WMOJ was on the 94.9 frequency, it was branded "Mojo 94.9", and used a rhythmic oldies format that appealed to both the black and white demographics. This station had very high ratings until its demise. After the station's move to 100.3 FM in 2006, the station took an urban adult contemporary format while retaining the "Mojo" branding and WMOJ call letters. WMOJ has since began to carry the Tom Joyner Morning Show, which is now simulcasted on WDBZ, which originally aired it by itself. On December 6, 2010, WMOJ shifted its format to rhythmic oldies, still under the "Mojo 100.3" branding.
On November 6, 2012, at 11:49 PM, WMOJ began stunting with Christmas music as a prelude to a flip to CBS Sports Radio on January 2, 2013, branded as "Holiday 100.3". The final song on "Mojo" was "Caribbean Queen" by Billy Ocean, while the first song on "Holiday" was "Rockin' Around The Christmas Tree" by Brenda Lee. The station's call letters were changed to WCFN on November 14, 2012 to reflect the forthcoming format. The station, as "FM 100 The Fan", launched at 12:01am on January 2. As of January 6, WCFN became the radio affiliate for road games and all playoff games of the Cincinnati Cyclones of the ECHL. WCFN was also the Cincinnati affiliate for Miami RedHawks men's basketball.
Shortly before Noon on July 30, 2013, WCFN changed their format to urban oldies, branded as "Old School 100.3". This ended the Sports format after just 7 months due to low ratings. It received a 0.2 rating in its first month, and a 0.1 each month following until its demise. The call letters were changed to WOSL on August 15, 2013.
