KDKA-FM (93.7 MHz, "93.7 The Fan") is a commercial FM radio station licensed to serve Pittsburgh, Pennsylvania. The station is owned by Audacy, Inc. through licensee Audacy License, LLC and broadcasts a sports radio format. Studios are located at Foster Plaza near Green Tree (west of Pittsburgh) while the broadcast tower used by the station is located near Mount Washington, next to its former studios in Pittsburgh's South Shore neighborhood at (40°26′28.2″N 80°1′31.2″W / 40.441167°N 80.025333°W / 40.441167; -80.025333).

KDKA-FM serves as the flagship station for the Pittsburgh Pirates Radio Network and the University of Pittsburgh Panthers IMG radio network. It broadcasts in the HD Radio format and simulcasts the news/talk programming of co-owned KDKA (1020 AM) on its HD2 subchannel, while the national network feed of CBS Sports Radio is heard on its HD3 subchannel.

KDKA-FM also carries Infinity Sports Network programming late nights and on weekends.

In 1948, the station signed on for the first time as WKJF-FM. In the earliest days of FM radio, while most were co-owned with an AM station, WKJF was an independently owned FM station. For a brief time, there was a co-owned UHF TV station, WKJF-TV (now WPGH-TV), which operated from 1953 to 1954. WKJF changed its call sign to WKOI in 1973, and then to WJOI (standing for "Joy") in 1974. Through the 1960s and 1970s, the station programmed a beautiful music format. During the 1960s, Bill Hillgrove, who would later become a Pittsburgh sportscaster, was a staff member and hosted a Saturday night big band show titled "Stereo Dance Party".

In 1978, WJOI was acquired by EZ Communications, which primarily owned easy listening stations across the country. By the early 1980s, EZ Communications observed that the easy format was attracting an increasing number of older listeners, that were not sought after by most advertisers, and began to switch its stations to formats that would attract younger audiences.

At midnight on April 5, 1981, WJOI became WBZZ, and was rebranded as "B94". The first song played after the format switch was "It's Still Rock and Roll to Me" by Billy Joel. B94 became Pittsburgh's number one Top 40/CHR station, tailoring its programming to not only a younger audience, but also a Pittsburgh audience, and quickly overtook its competitors, including WXKX and WPEZ. B94 was also an affiliate of The Rockin' America Top 30 Countdown with Scott Shannon throughout the 1980s, as well as Open House Party with John Garabedian during the 1990s.

B94 featured local morning shows such as "Quinn and Banana" (hosted by Jim Quinn and "Banana" Don Jefferson) from its debut in 1983 until 1993, and "JohnDaveBubbaShelley" (hosted by John Cline, Dave Kaelin, Marc "Bubba" Snider and Shelley Duffy, along with some minor personality changes) from 1993 through 2004. In addition, the station featured a mostly local air staff who were born and/or raised in the area.

EZ Communications merged with American Radio Systems in July 1997, with ARS merging with Infinity Broadcasting (owned by CBS Radio) in September of that year. (Infinity was renamed CBS Radio in December 2005.) In 1998, the station relocated from its longtime studios on Mount Washington to Foster Plaza in Green Tree.
