By Gregg's definition above, Ballance would be considered "hot talk"
The term "hot talk" came out of the talk formats in the mid-90's that tried to combine Howard Stern or a pseudo-Stern equivalent in mornings with lifestyle talk the rest of the day. The difference here was that the format was, like Stern, targeting 18-34 males. And that was not then any more than it is now, the target of traditional talk stations.
When Stern left terrestrial radio, those few stations that had achieved success in the format were unable to sustain the ratings. The further experiment by CBS to create Sternless hot talkers was a failure.
While we point to Trenton and Orlando as present day hot talkers, they really are not... they are just less political talk stations that have rather similar demographics as other more conventional talkers. WKXW is 10th in 18-34 but #1 in 35-64.
Bill Ballance typically delivered 25-54 women going back to the early KGBS days. That is not the "Hot Talk" target.
