Here is a question for you then. The over 55 group seems to be highly discriminated against in the radio universe for God knows how long. Why? I'm not 55 (and still a ways away), but I think what a 55 y/o liked several generations ago isn't the same as a 55 y/o likes now. Meaning, the demo has evolved. As such, this opens up more potential format options, one of them a classic rocker or even more modern Adult Contemporary type formats. This isn't the day where 55+ listen to chamber music anymore.
And most in that age range have actual money to spend in bigger things and in larger quantities on products and services than the 18 - 34 group that lives on vape options, social things and alchohol while still living in their 55+ parents basement living well beyond their credit limits.
