KTDY

KTDY signed on on September 15, 1966 as KPEL-FM, and was at first a beautiful music simulcast of sister station 1420/KPEL. In the early 1970s, due to Federal Communications Commission (FCC) regulations discouraging full AM/FM simulcasts, KPEL-FM began programming a Progressive Rock format in the overnight hours, retaining the beautiful music format during the day. Eventually, KPEL-FM changed its calls to KTDY in early 1977, and the progressive format was expanded to broadcast the entire day. In 1979, KTDY began testing a three-hour nightly disco format called "the Electric Disco." The disco experiment lasted only a year before KTDY shifted to become Acadiana's first FM Top 40/CHR station under their moniker as "The New KTDY FM 100, Today's Radio!". In short of weeks the new KTDY was beating KSMB by four years. The Disco show lives on Friday mornings in an all-request show titled "The Polyester Power Hour" (or Poly Po Ho, for short). After KSMB switched to their new & improved top 40/CHR format in October 1984, the two stations were engaged in a heated format competition until KTDY shifted from CHR to their now legendary AC as "The All New Magic 100 KTDY" in 1986.

Since shifting to AC, KTDY has tweaked the format back and forth from mainstream AC to oldies-based Soft AC in the early 1990s to Hot AC in 1998, then back to mainstream AC in 2000.

KTDY at one point aired American Top 40 With Casey Kasem, King Biscuit Flower Hour, Record Report and the Special of the Week with Robert W. Morgan, Scan, Powerline, Earth News, Dr. Demento, Off The Record With Mary Turner, 60 Second LP, and in the early days of the station a strange, daily comedy serial called Kremmin of the Star Corps which turns out was created by well known BBC personality Kenny Everett. Currently, the Polyester Power Hour is the blockbuster on Friday mornings with CJ. KTDY launched their app in 2017.

An Ibiquity-licensed station, KTDY began broadcasting HD Radio in August 2007. KTDY was the first commercial station in the Acadiana market to do so, and was the second overall, after KRVS. Currently, KTDY does not multicast. However the DJs have reported that multicast is coming (date and how it will be used is unknown at this time).

Its morning show was hosted by CJ and Debbie Ray until late 2018, when Debbie Ray retired. She was replaced temporarily by Emily J, who has since relocated with her husband due to a military transfer. As of August 2019, the search for a morning show co - host was still underway. The mid-day show is hosted by Steve Wiley. The afternoon drive time is hosted by JayCee, who in 2013 was tagged by The American Lung Association as Southwest Regional's "Volunteer of the Year".
