The station signed on the air April 1, 1948, as WCSC-FM. It was the FM sister to AM 1390 WCSC. WCSC-FM was Charleston's second FM station, going on the air a year after 95.1 WTMA-FM. WCSC-AM-FM were CBS Radio Network affiliates, simulcasting CBS's schedule of dramas, comedies, news and sports. As network programming moved from radio to television, WCSC-AM-FM switched to a full servicemiddle of the road format of popular adult music, news and sports. In the late 1960s, the Federal Communications Commission began requiring FM stations to end their simulcasts. WCSC-FM switched to a beautiful music format. To give it a separate identity from WCSC, the FM station became WXTC-FM in 1973, calling itself "Ecstasy." In the 1990s, WXTC-FM switched to soft adult contemporary. It later flipped to smooth jazz and a few years later, playing 1970s oldies. In the 2000s, adult contemporary music was the format. The AC format was dropped on October 11, 2007 and the DJs were dismissed. The station then continued playing AC music with liners directing listeners to sister station 95.1 WSSX. The next day, a country music format was launched as "96.9 The Wolf." This came shortly before Citadel Broadcasting moved its Charleston country outlet, WNKT, into the Columbia, South Carolinaradio market. With the change to The Wolf, Citadel Broadcasting had a country music station in the Charleston market, even after WNKT relocated, to compete with rival country music station WEZL, owned by Clear Channel Communications. However, the changes left Charleston without any adult contemporary radio stations. Shortly after the flip to country, the WSUY call letters were changed to WIWF. WXLY 102.5 FM soon became an adult contemporary station. Citadel merged with Cumulus Media on September 16, 2011. On February 3, 2014 WIWF, along with nine other Cumulus owned country music stations, made the switch to the "Nash FM" branding. Jessica Chandler and Jay Shadix moved to afternoons as their morning show was replaced by America's Morning Show. On November 19, 2018, WIWF dropped the "Nash FM" branding and the country music format. It returned to the "96.9 The Wolf" branding, and began playing Christmas music for the holiday season. On December 26, 2018, WIWF launched a classic hits format, retaining the "Wolf" branding. WIWF also brought in the syndicated John Boy & Billyradio show for mornings, based at WRFX in Charlotte, North Carolina.
