In 1997, EZ Communications was purchased by American Radio Systems, who would later merge with Infinity Broadcasting, which in turn was acquired by CBS Radio. From March 1979 to October 2017, KYKY was the home of the Phillips & Company (originally Phillips & Wall) morning show, hosted by long-time St. Louis radio host Guy Phillips. Phillips was inducted into the St. Louis Radio Hall of fame in 2005. In January 2010, KYKY's slogan was changed from "Your Music, Your Y98" to "More Music. Better Variety". Around 2010, KYKY changed its slogan to "Today's Best Music".
