WBCT

The station began operations in October 1951[4] as WJEF-FM, simulcasting sister station WJEF (1230 AM, now WTKG). In 1960, WJEF-FM broke away from the simulcast and began playing classical music. That year, the station increased its power to 500,000 watts. This was under the ownership of John Fetzer, who also previously owned WKZO-TV (now WWMT), WWTV-FM (now WJZQ) in Cadillac, and the Detroit Tigers baseball team. WJEF also owned and operated a Muzak franchise it broadcast on a sub-carrier.

In the mid-1960s, the station, then known as WJFM, switched to a MOR/news/talk/sports format, and in 1967 became more music-intensive, adopting the moniker "The Modern Sound," which Fetzer reportedly soon did away with because he felt the station played too much "rock and roll." From that point and through much of the 1970s, apart from an automated country format in 1971–1972, WJFM was primarily a Beautiful music station. Despite its strong signal, the station usually hovered near the bottom of the ratings during this time.

WJFM changed to an automated Top 40 format in 1977, and then adult contemporary music the following year as "Mellow 93", picking up the format that had been abandoned by WMLW in its switch to WFFX earlier that year. "Mellow 93" proved a moderate ratings success, with the station usually around fifth or sixth place.

The AC format lasted until the station called in a consultant, who attempted a format change to Top 40/CHR in 1984. The change on the airwaves not only included the music selection, with most of the staff either quitting or being let go. With the Grand Rapids area flooded with CHR stations at the time, as WGRD, WSNX and WKLQ were all playing Top 40 music, WJFM's CHR format lasted only two years before the station went back to Soft AC as "The New Joy FM." The "Joy" format also proved a failure, and in 1988, WJFM became a classic hits station. Ratings for the classic hits format were initially very good but soon dropped off, and in 1990, the station evolved to classic rock.

Fetzer died in 1991, and his family sold the station a year later. In June 1992, Billboard magazine reported that a number of key WJFM staffers, including general manager Joel Schaaf, program director and midday host Sean Stevens, and morning man Jeff France, had left the station, and rumors began swirling to the effect that the classic rock station would go country to take on incumbent country powerhouse WCUZ. Sure enough, on July 24, 1992, the classic rock format was dropped for country, and WJFM became WBCT as "B93". B-93 has ranked number one or number two 12+ ever since. Lee Cory was the original program director, and Neal Dionne and Reese Rickards were the original B-93 morning show hosts. They worked mornings for 22 years before having their jobs eliminated in a round of budget cuts initiated by current owner, iHeartMedia.
