From a Bridge Rating study of America’s first JACK station in Denver:
“KJAC-FM is converting over 50% of its weekly audience to favorite station status. Conversion at this level is unique to this format.”
Their conclusion after one year: JACK has legs.
The ratings for JACK in Denver don’t look as sweet as the Bridge Ratings’ glowing report would predict. Denver is a fairly special case because the signal is marginal, but the fact remains: JACK in Denver may have legs, but he also walks with a limp.
