B94 KDKA FM Pittsburgh aircheck 1993

WBZZ "B94"
At midnight on April 5, 1981, WJOI became WBZZ, using the moniker "B94." As a Top 40 station, B94 soon overtook its competitors, including 96.1 WXKX (now WKST-FM) and 94.5 WPEZ (now WWSW-FM). B94 became the city’s number one Top 40 station, tailoring its programming to not only a younger audience, but also a Pittsburgh audience.The first song played after the format switch was "You May Be Right" by Billy Joel.

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 “John, Dave, Bubba, Shelly” (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 became part of CBS Radio in December 2005.) In 1998, the station relocated from its longtime studios on Mount Washington to Foster Plaza in Green Tree.

In 2004, Clear Channel Communications cancelled The Howard Stern Show on its longtime Pittsburgh outlet, 105.9 WXDX-FM. In response, WBZZ operations manager Keith Clark decided to flip WBZZ’s format after 23 years as a Top 40 station. Clark wanted to pick up Howard Stern to improve the station's ratings and unveiled a new active rock format known as "93-7 K-Rock" to compete with Clear Channel’s other Pittsburgh rock stations.

At 8 a.m., on June 30, 2004, WBZZ’s on-air talent gathered to say goodbye to Pittsburgh, thanking the city for its support throughout the years. WBZZ ended the Top 40 format at 8:30 a.m. with "Move This" by Technotronic. K-Rock's first song was "For Those About To Rock" by AC/DC. Listeners who were fans of WBZZ but didn't like the new rock format were encouraged to listen to sister station WZPT. The WBZZ call sign was replaced by WRKZ on July 7, 2004. Ratings for the station improved initially after the switch, but began to decline before Howard Stern's departure for Sirius Satellite Radio.


At 10 a.m., Monday, October 1, 2007, after the Opie and Anthony Show ended, WTZN began stunting with Christmas music, in anticipation of a format flip scheduled for later that week.[12] The station made some fairly obvious hints as to the future of the station, advertising "Something's missing in 'Pitts-urgh'," and asking, "What is missing in Pitts-urgh?" Listeners were prompted to go to www.pitts-urgh.com, where there was a message board asking "What do you miss the most about Pittsburgh?" Among the choices was "B94 Radio."
B94 returned to Pittsburgh the following Friday, October 5, at 5 pm, with its first song being Justin Timberlake's "SexyBack."This marked CBS Radio's first Top 40 switch after the failure of Free-FM. CBS would later launch the format in Houston (KKHH), San Francisco (KMVQ-FM), New York City (WXRK), Los Angeles (KAMP-FM), Detroit (WVMV), Boston (WODS), Orlando (WJHM) and Philadelphia (WZMP) before 2017. The return of B94 was apparently part of a CBS Radio initiative of resurrecting radio stations that had been killed off for other formats, such as WCBS-FM in New York and KFRC-FM in San Francisco. However, unlike those stations, which aired oldies/classic hits formats, B94 played current hits.

On November 27, 2007, WTZN switched its call sign to WBZW-FM to reflect its new format. B94's former call sign, WBZZ, had been taken by an Adult Contemporary radio station in Malta, New York. That station is now WQSH. CBS Radio later reacquired the call sign for use on 100.7 in Pittsburgh, which had been WZPT.

On January 19, 2010, CBS Radio announced it would drop the B94 branding again, and would flip the format to sports talk, launching February 15, 2010 under the name "Sportsradio 93.7 The Fan".The change was part of an initiative by CBS to establish FM sports talk stations across the country.
