In 1969, Richard J. Miller, owner of AM station KXLW in Clayton (now KSIV), acquired KADI and relaunched it with a progressive rock format.

The fans of the much-talked about duo immediately followed them down the dial from WKKX (106.5 FM) to 96.3, and lifted KIHT from tenth place to first in persons 25 to 54 in only one ratings period upon the release of the Arbitron Fall 2000 book—a feat that continues to go unmatched in St. Louis radio history.

On January 30, 2015, at 5 a.m., after playing "Rock'n Me" by The Steve Miller Band, "Get The Party Started" by P!nk, and "Mama Said Knock You Out" by LL Cool J, KIHT flipped to an adult-leaning Top 40/CHR as "Now 96-3".

As part of the terms of the deal, Entercom would take over operations via a local marketing agreement on November 23; however, as the station itself will remain with Urban One, it was announced that the Adult R&B format and WFUN-FM's intellectual property would move to KNOU on that date.

The change took place at midnight on November 23; subsequently, Gateway Creative Broadcasting announced it would purchase WFUN-FM's former frequency and flip it to Christian Rhythmic CHR under the "Boost Radio" branding in January 2021.
