 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.
