102.1 FM, known as WZAT, signed on in 1971 as a completely automated Top 40 station with the locally popular "Breakfast With Burl" program as the only exception. Airstaff was gradually added, and between a strong AM station (WSGA), and a slightly lighter top 40 station in the late 70's as WSGF 95.5, a real format war ensued. By 1986, 95SGF had become modern-day rocker WIXV, and AM 1400 had quickly moved out of the format during the death of AM top 40 in 1982. In the 1980s-early 90's, "Z102" was the dominant (and often only) Top 40 station in Savannah. Stations like 99.7 WHTK, Kiss 98.7, Wave 97, and Blu 92 all tried and (mostly) failed in taking on the popular Z102.
In 1992, the station was sold and flipped to Modern Rock as "WZAT (or later, Z102) - Savannah's Rock and Roll Radio" and, alternately, "Z102" and was a very popular Alternative rock station. Phoenix Media Partners sold the station to Cumulus in 1997. Upon the sale to Cumulus, the station repositioned as Top 40. The station has since been Top 40 and Top 40/Hot AC hybrid twice since then; it flipped to Hot AC on March 11, 2008. The next day, the station revealed its new name and positioner, which was "Mix 102-1 - The Best Mix of Music." On October 1, 2010 WZAT began stunting in preparation of a new format. On October 4, 2010, 102.1 became a sports talk station carrying ESPN Radio. On January 2, 2013, 102.1 began carrying CBS Sports Radio.
