The station signed on the air on January 1, 1974 as a sister station to WIBX and ran a beautiful music format under the call lettersWIBQ. The station abruptly changed format in 1985 to classic hits as "Z 98.7" with the call letters WNYZ. After a while in the format, WNYZ next flipped to a rock-leaning Top 40 format, identifying as "New York's Z-98.7". The format began with Twisted Sister's We're Not Gonna Take It, followed by Quiet Riot's Cum On Feel the Noize. The Top 40 format could not, however, compete against powerhouse Top 40 station Power Hits Rock 107, and in 1989 the station again changed format. Originally the station planned to join the 'Z-Rock' satellite Heavy Metal format available at the time, but instead flipped to their current format of hot AC and current callsign WLZW, identifying as "Lite 98.7".
As Lite 98.7
Lite 98.7's calls and format reflects its first slogan "Lite and Easy Favorites". In its early years, Lite 98.7 competed with rival AC station and market leader KG 104 WKGW. WLZW quickly toppled WKGW from its position, and by 1993 WKGW had flipped to classic rock as WKFM, formerly in Syracuse, New York took over the 104.3 frequency. WLZW was then the only AC station in the Utica-Rome market until the spring of 1994 when WUUU which switched frequencies from 93.5FM to 102.5FM with WKDY the previous year, flipped format from oldies to adult contemporary to become "Warm 93.5". While WUUU/WRFM was a more softer AC station, WLZW was a somewhat more upbeat station. After over 8 years of competition between the two stations, WRFM flipped format and call sign onDecember 26, 2002, becoming oldies station WUCL again leaving Lite 98.7 as the only AC station in the market. This lasted over a year until WRBY flipped their format to hot AC and call sign to WUMX, identifying as Mix 102.5. In order to compete with WUMX's popular "Christmix 102.5" holiday programming, WLZW began switching to a Christmas Music format in 2009. Traditionally, WLZW switches on or around Thanksgiving Day and continues with Christmas music until Christmas Day. In 2015, WUMX tweaked their format and dropped their holiday music programming, leaving WLZW as the only station in Utica-Rome to broadcast Christmas music.
