Other stations in the early 1980s which utilized the "Hot Hits" concept included: WFEC-AM (1400), Harrisburg, PA ("Fire 14"); KITS-FM (105.3), San Francisco ("105 Kits," prior to the adoption of the station's long-running Alternative Rock format); WMAR-FM (106.5), Baltimore (later also as WMKR, "K106"); and WNVZ-FM (104.5), Norfolk/Newport News, VA ("Z104"). WFEC, which had been a successful Top 40 station in years past, was not consulted by Mike Joseph although it was modeled after WCAU-FM and followed the basics of Joseph's formula to the letter. The format's success also inspired imitators, such as the Rick Peters-derived "Hit Radio" approach utilized at a number of CBS-owned FM stations, including WHTT (formerly WEEI-FM) Boston, KHTR St. Louis, and KKHR Los Angeles, in the mid-1980s.
