After “Groove 103.1” flipped back to Dance, the station’s ratings began to improve, albeit slightly. It eventually peaked at a 0.9 share 12+, which (tied with one of the previous formats on the 103.1 duo) represents the highest ratings ever achieved by the two 103.1 FMs. Apparently, this success got the attention of Jacor (now Clear Channel), owner of CHR/Pop KIIS-FM. In September 1998, Jacor purchased KACD and KBCD from Ken Roberts. Shortly thereafter, on October 12, 1998, Jacor switched “Groove 103.1” to a simulcast of KIIS-FM, and eventually debuted a AAA format under the name “Channel 103.1”.
One side note: in an article which appeared on laradio.com, KIIS-FM General Manager Roy Laughin admitted that Jacor bought Groove 103.1 and changed the format so that it KIIS-FM’s ratings would improve, due to the loss of a competitor.
