WPLJ 95.5 NEW YORK   "Jim Kerr"   August 12, 1986 Part 2

Not too long after Emmis bought KMGG, it immediately saw a niche to counter top 40 stations KIIS and KKHR and urban outlet KDAY, KJLH, and KACE (the latter three all signal challenged). On January 11, 1986 at 6 p.m., KMGG dropped its adult contemporary format and became the first-ever rhythmic contemporary-formatted radio station with new call sign KPWR and branding "Power 106".
The first song on the newly christened "Power 106" was "Say I'm Your Number One" by Princess. Jay Thomas was hired as the host of "The Power 106 Morning Zoo". 
Power 106's first slogans in 1986 were "Turn on the Fresh New Music Mix", and "I've Made the Power Switch".

After briefly registering successful ratings during its first six months as Pirate Radio, KQLZ soon garnered ratings too low to bill advertising rates high enough to sustain operating costs. 
By late 1989, the station focused more on hard rock and heavy metal music (mostly metal in the more pop oriented glam metal genre), putting it in direct competition with metal station KNAC and album rock outlet KLOS. 
Shannon and most of the original on-air personalities were dismissed on February 13, 1991.

In 1986, KROQ was purchased at a then-record $45 million by Infinity Broadcasting.
 By the late 1980s, the station had started dipping in the ratings. New wave had declined in popularity and electronic dance bands, such as Depeche Mode and New Order, started getting more airplay on the station. Also during this period, KROQ began focusing on college rock (or so-called alternative rock) by adding bands into their playlist such as R.E.M., the Red Hot Chili Peppers, The Psychedelic Furs, ABC, The Smiths, Frankie Goes to Hollywood, Bronski Beat,Echo & the Bunnymen, The Replacements, Camper Van Beethoven, Jane's Addiction, the Pixies, The Alarm, The Cult, Violent Femmes, Love and Rockets, Dramarama, and Social Distortion, as well as heavier acts like Faith No More and Living Colour and guitar-oriented hip-hop groups like Run-DMC and the Beastie Boys.

KRTH 101.1 LOS ANGELES "Dan Taylor"  April 8th 1991

By mid-1995, KYSR adjusted its format by dropping most of the rhythmic and soft rock tunes, shifting to a pop-leaning modern rock direction, minus the harder approach embraced by the more mainstream alternative KROQ. 
This version of Hot AC was called "modern adult contemporary" and became one of the first stations in the U.S. with the format.
