He talks about commercials as being part of programming. He's right, and that's why some advertisers aiming for that demo create program-length commercials aka infomercials. They want their messages to stand out, and in the context of typical music programming, such as oldies or classic hits, their :30 messages simply become part of the stop-set. That's why that kind of programming isn't the right environment for the messages he's talking about. The right environment is talk programming. That's where those messages will fit with the environment. That's why talk radio programming can make more money for radio than oldies.
Imagine listening to an oldies radio station, and hearing all those great songs from your youth. All of a sudden the music stops, and commercials come on talking about funeral homes and drugs for prostate health. Talk about a rude awakening. Does that get you in the mood for buying something? Probably not.
But the real issue here, and Holland doesn't address it at all, is that the demo he's talking about HATES commercials. They HATE being sold products. When the phone rings and it's a sales pitch, they hang up. When the music stops and commercials start, they turn off the radio. They're not influenced by advertising. They prefer self-discovery. They prefer word of mouth. They prefer to have people they trust share information with them. That process works better in talk radio than it does in music radio. And the TIME it takes to deliver that message works better in talk radio.
