History Early years (1955-1970s) The station signed on in 1955. In the early 1970s, it switched to a Top 40/Oldies format. Rock (1976-1981) In 1976, the station became WSAI-FM and played Rock n Roll. Country (1981-1985) In 1981, the station changed to a country format, and became WKXF ("Kix 94.1"). Top 40 (1985) During late summer 1985, the station briefly switched to a CHR format branded as "K-Rock 94". Adult contemporary (1985-1997) Several weeks later on August 26, 1985, the station switched to Adult Contemporary WWNK ("Wink 94.1"). Hot adult contemporary (1997-2006) On September 19, 1997, WVMX ("Mix 94.1") made its debut with a hot adult contemporary format that was patterned after then-sister station WMVX in Cleveland. In 2006, the station started leaning towards Rhythmic AC after the station had begun carrying Whoopi Goldberg's Wake Up With Whoopi show. Modern adult contemporary (2007-2009) The station became "Radio 94.1" at Noon on September 10, 2007, changed call letters to WNNF and dropped Goldberg's show as the station flipped to Modern AC. The first song on "Radio" was "Possession" by Sarah McLachlan. On August 1, 2008, then-owners Clear Channel put WNNF up for sale, along with sister station WOFX, to settle regulatory issues involved with the company's sale to private equity firms. On January 3, 2009, Cumulus Media was chosen as a buyer and swapped five of the company's radio stations in Wisconsin to make this transaction complete. Adult album alternative (2009-2011) On March 8, 2009, the station began calling itself "Renew 94.1", asking listeners' input on what path the station should take on its website. Later that month, it relaunched its format as "Frequency 94.1", but with a slight difference than what it was as "Radio". The station had a slight adult album alternative (AAA) lean, patterned from Cumulus's recently launched AAA stations in Houston and Nashville, which later evolved into a full-fledged AAA in late 2009, dropping most pop acts and leaving competitor WKRQ as
