KTWV  KTWV (94.7 FM, ("94.7 The Wave") is a commercial FM radio station that is licensed to Los Angeles, California and broadcasts to the Greater Los Angeles area. The station is owned by Entercom and airs an urban adult contemporary radio format. KTWV has studios on Wilshire Boulevard in the Miracle Mile district of Los Angeles, and its transmitter is located on Mount Wilson. KTWV is known for pioneering the smooth jazz radio format in the late 1980s. KTWV broadcasts in HD Radio. On March 7, 1961, KLAC-FM first signed on the air. It served as an FM sister station to KLAC (570 AM), simulcasting its programming. KLAC-AM-FM were purchased by Metromedia in 1963. By the mid-1960s, the FCC wanted FM sisters to AM stations to air separate programming; thus, KLAC-FM became an automated station, playing a mix of middle-of-the-road and big band music like other FM stations owned by Metromedia. In order to separate itself further from its AM sister, the station changed its call letters to KMET in 1968. A few months after the station adopted its new call sign, Tom Donahue convinced Metromedia to establish a freeform rock format on KMET and KSFR in San Francisco (which then became KSAN) after a dispute with the owners of KPPC-FM. Donahue brought over most of those who went on strike at KPPC, including his Los Angeles tag team partner in former KFWB "Swinging Gentleman" B. Mitchel Reed. He had become enamored with the underground rock sound after attending the Monterey Pop Festival and shortly afterward bonded with fellow top 40 veteran Donahue over their increasing unhappiness with AM radio and its restrictions. KMET became legendary and popular as "The Mighty 'MET" for its freeform style in letting DJs choose the music without genre restrictions and an irreverent, loose and laidback presentation of the music. In the early 1980s, however, Metromedia changed the presentation and sound of KMET to a more conventional album-oriented rock (AOR) format. In the process, KMET quickly became a shell of its former self: playlists were tightened and hit-oriented, disc jockeys became less personal in their presentation, and the station was heavily constructed by outside consultants. This drove KMET's ratings down to the point of being well behind established AOR pioneer KLOS as well as behind KROQ-FM, a station that rose from the ashes of KPPC-FM to become the trademark radio home in Los Angeles for the new wave and punk scenes in the 1980s.
