WZLX (100.7 FM) is a classic rock radio station in Boston, Massachusetts. WZLX was one of America's first classic rock FM stations. Its studios are in Medford, and its transmitter is atop the Prudential Tower.
What is now WZLX was originally WCOP-FM, notable for being one of the first FM stations to break simulcasting with its AM partner. WCOP-FM's separate programming was initially classical music and was one of the first FM stations in the region to (briefly) broadcast in FM stereo (the station would resume stereo programming in the early 1970s).
In 1965, WCOP (AM) had become Boston's affiliate for the NBC Radio Network, and WCOP-FM would often simulcast the hourly NBC Radio newscasts. By 1969, NBC Radio's weekend series Monitor had moved from WCOP to WCOP-FM, to allow the former to broadcast more hours of country music on the weekends.
The station went through a number of format changes (and later callsign changes), including beautiful music in the late 60s until 1973, oldies (as “Total Gold 101, WCOP-FM”, 1973–74), country 1974–76), AOR (as WTTK "TK101" 1976–78), beautiful music (as WHUE, 1979–85), and Top 40 (as WKKT "The Cat", for a few months in 1985). Also, just before the switch to WKKT in December 1984, the station (as beautiful music station WHUE) sought and received the WCOZ call letters formerly on 94.5. Ironically, those calls belonged (legally) to the 100.7 frequency for just 2 weeks in December 1984.
100.7 FM adopted its current format and callsign, WZLX, in mid-October 1985. Station owners First Media Corporation hired Gary Guthrie as the architect of its Classic Hits format, a format aimed at people who experienced adolescence in either the 1960s and 1970s and enjoyed the music of those eras, but did not care for the then-current heavy metal or top 40 'hot hits' of the 1980s. These were people whose mindset was getting too old for AOR and top 40, but were too young for or not interested in oldies. WZLX is considered one of the classic rock format's earliest success stories as reflected by the station's 19th to 2nd place climb in the Adults 25-54 demographic in its first ratings period.
In 1986, Guthrie spread his concept of the format to other radio stations he consulted and Bill Smith was hired to be the station's program director and morning personality. Guthrie would return in 1990 for an additional on-site stint to repair the station's ratings.
In 1997, WZLX radio host George Taylor Morris created a media frenzy about the "Dark Side of the Rainbow" phenomenon, in which Pink Floyd's album The Dark Side of the Moon is said to synch up with the movie The Wizard of Oz.
In 2005, WZLX, along with sister stations Mix 98.5 and what was then Oldies 103.3, were rumored to flip to CBS Radio's ever-expanding "Jack FM" format. Had WQSX (now WEEI-FM) not flipped to the format as "93.7 Mike FM" on April 14, WZLX might have flipped to the format the next day as 100.7 Jack FM.
In the spring of 2007, WZLX became the first station in the country to broadcast programming in full digital 5.1 surround sound. This flagship effort coincides with the recent move of the industry to implement the HD Radio format.
From 1991 to 2007, the station had its studios on the 24th floor of the Prudential Tower in downtown Boston, the location of its transmitter. On March 3, 2007, the station moved crosstown to the facility where sister stations WODS and WBCN are clustered in the CBS studios in Brighton. The transmitter is still atop the Prudential Tower.
On February 2, 2017, CBS Radio announced it would merge with Entercom (which locally owns WEEI, WEEI-FM, WKAF, WRKO and WAAF). On October 10, CBS Radio announced that as part of the process of obtaining regulatory approval of the merger, WZLX would be one of sixteen stations that would be divested by Entercom, along with sister stations WBZ and WBZ-FM, as well as WRKO and WKAF (WBMX, WODS, WEEI AM and FM, and WAAF will be retained by Entercom, while WBZ-FM will be traded to Beasley Broadcast Group in exchange for WMJX). On November 1, iHeartMedia announced that they will acquire WZLX, WBZ (AM), WRKO and WKAF. To meet ownership limits set by the FCC, iHeart will place WKOX into the Ocean Stations Trust in preparation for a sale to a permanent buyer. The merger was approved on November 9, 2017, and was consummated on the 17th. iHeart then began operating WZLX, WBZ, and WKAF under a local marketing agreement. The sale of WZLX, WRKO, WKAF, and WBZ to iHeart was completed on December 19, 2017.
There have been a few morning shows on the station in recent history. With the coming of Howard Stern to WBCN in the early '90s, the Boston legend Charles Laquidara and his show, The Big Mattress, took up residence at 'ZLX. With Charles's retirement, the short-lived Mornings with Tai and Steve Sweeney eventually gave way to Steve Sweeney's Neighborhood, (co-hosted by Lance Norris) which ended a 5-year run in 2005. Longtime morning team Karlson and McKenzie took over on August 1, 2005.
Sports conflict broadcasts
Beginning in October 2013, WZLX will also carry Boston Celtics games that conflict with Boston Bruins games. Games will be produced by sister station WBZ-FM (which is the flagship for both teams). In addition, some Bruins games conflicting with WBZ-FM's New England Patriots broadcasts have aired on WZLX since 2011 (previously, WBZ served this function).
WZLX previously aired a freeform rock format on its HD3 subchannel called WBCN which continued the name of the former Boston AOR station. On January 29, 2016, WZLX-HD3 switched to an adult standards format as "The Lounge". After the sale of the station to iHeart was completed on December 19, 2017, the HD3 channel was removed.
