The station first began broadcasting in 1962 as WMAX-FM, then became WYON as a sister station to WION in Ionia, Michigan in 1965. In 1976, the station was purchased by the owners of WCUZ 1230 and became WMLW, a soft rock/adult contemporary station. WMLW switched to album oriented rock as WFFX "The Fox" in 1978, and then to country music in 1980 as WCUZ-FM dropped the "Country Gold" format on September 24, 2000, and debuted classic rock "101.3 The Fox" that afternoon following coverage of the MBNA.com 400 NASCAR Winston Cup event. They changed call letters to the current WBFX on September 27, 2000. The lineup at the debut was Bob and Tom, Ranger Bob, Aris Hampers and Otto Mation and Alison Harte. Others jocks over the decade would include Matt Hendricks, Jack Lawson, Mark Fuerie, Andy O'Riley, Shafee and Joe Daugherty. The station also featured Nights With Alice Cooper for several years in the evenings. Since its inception, WBFX has changed its music style multiple times, although all remained loosely in the classic rock genre. In late June 2009, the station adjusted its format towards mainstream rock, with a mix of harder classic rock songs as well as recent rock music from the 1990s and 2000s. This adjustment was in response to the localactive rock station WKLQ changing formats to sports talk. By 2010, however, Townsquare Media's WGRD-FM adjusted its format to active rock from alternative rock, and saw a decent rise in the ratings, while WBFX remained roughly the same. After this, WBFX rebranded as "The Next Generation of Classic Rock", and adjusted their playlist back towards having a more traditional classic rock feel, taking on WLAV-FM. On February 20, 2013, WBFX began running liners advising listeners that "The Fox dies Friday". At Noon the next day, after playing "The Breakup Song" by the Greg Kihn Band and "The Final Countdown" by Europe, the station rebranded as "101.3 The Brew", with an acknowledgement of Grand Rapids being voted as 2012's "Beer City USA" according to a poll conducted on Examiner.com and the noteworthy rise of the popularity and economic impact of microbreweries in the region. The station launched with "Enter Sandman" by Metallica. Musically, the station was tweaked with more rock titles from the 1980s and 1990s added into the playlist. The presentation and formatics are similar to other stations called "The Brew" that Clear Channel has deployed in places such as Portland, OR, Columbus, OH and Wichita, KS. With sister station WMAX-FM having taken the ESPN Radio affiliation in recent years, WBFX continues to air NASCAR Sprint Cup Series races, as they have for over a decade. On July 6, 2015, WBFX tweaked their format towards an active rock-leaning mainstream rock presentation. While titles going back to the 1960s were occasionally played, the emphasis was strongly on rock music of the 1990s and 2000s. The ratings slid heavily a few months after this prior tweak in the format. On February 16, 2016, WBFX shifted the format back to classic rock, with emphasis on 1970s and 1980s rock music. They also changed the lineup of announcers to prefer locally-based ones instead. On January 23, 2017, the station added the Rover's Morning Glory hot talk radio show during morning drive time. On March 21, 2019, the station tweaked the playlist once again, eliminating much of the pre-1980s rock music and adding many well-known 1990s rock songs.
