KTDY (99.9 FM) is an adult contemporary music formatted radio station in the Lafayette/Acadiana market in Louisiana, United States, owned by Townsquare Media. Its studios are located on Bertrand Road in Lafayette, and its transmitter is located north of St. Martinville, Louisiana. The station's 100,000-watt signal allows it to be picked up clearly 24/7 in Baton Rouge, 55 miles to the east, and Lake Charles, 70 miles to the west. In Baton Rouge, the station competes against 96.1 The River. 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 format as "The All New Magic 100 KTDY" in 1986.
