What I always say when deficient or underperforming stations is mentioned is "Look at Proctor & Glamble"."Radio" doesn't program stations. People do. Some are good and some are bad. But you can't generalize. If you don't like what you hear, there are lots of available choices. Nobody forces you to listen. It's totally voluntary. But don't make judgements about people you don't know because of your personal taste.
The best marketer in the world introduces new products ("formats") constantly. They test market them extensively and do the world's best research. Yet half of them do not make it through their second year on the market.
Not every format will be #1. Not every format has to be #1 to make money. This is not a horse race; there can be 20 or more real winners in the larger markets.
