History
The station signed on the air in 1970 as KRNT-FM. It was the FM counterpart to KRNT. Both stations were owned by the Cowles family, publishers of the Des Moines Register. During those early years, Drake-Chenault's automated "Hit Parade" format was aired.In 1974, the station became KRNQ. That year, Cowles sold KRNQ and KRNT to Stauffer Communications of Topeka, Kansas. The two stations were sold to Saga Communications in September 1988. KRNQ was originally an automated Top 40 station. In January 1976, KRNQ began airing American Top 40 with Casey Kasem, and then Shadoe Stevens, until April 1989. In 1984, the automation ended and the station began using local DJs. By the end of the 1980s, KRNQ was at or near the top of the local Arbitron ratings.
In 1991, due to Saga's desire to reach older listeners, KRNQ's youthful Top 40 format was changed to a slightly older hot adult contemporary format and was known as "Q102/KRNQ, Today's Hits and Yesterday's Favorites". KRNQ promised to play no rap and no hard rock, both of which were very much a part of popular music at the time. This format change left Des Moines with no contemporary hits outlet for nine years, until KKDM's flip from Alternative to Top 40/CHR in 1999. KRNQ became KSTZ on June 25, 1993.
When the station re-imaged itself to adult contemporary on June 21, 1993, the positioning statement the station used was "Superstars of the 70s, 80s and 90s". The station later switched to "The Best Variety of the 80s, 90s and Today." In 2001, the station began using the current positioning statement of "Today's Best Variety", returning to a hot AC direction. With KKDM becoming more of a factor since its 1999 debut, KSTZ has adjusted its playlist and adopted an adult top 40 format by adding a limited amount of adult-friendly rhythmic music with artists such Rihanna and The Black Eyed Peas in the mix.
