On February 2, 2017, CBS Radio announced it would merge with Entercom (which locally owned 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 would be retained by Entercom, while WBZ-FM was traded to Beasley Broadcast Group in exchange for WMJX). On November 1, iHeartMedia announced that they would acquire WZLX, WBZ (AM), WRKO, and WKAF. To meet ownership limits set by the FCC, iHeart placed 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.
