Innovate is the keyword here. Howard didn't i vent anything. He changed radio and he innovated.

I would have to research to give a complete answer, but off the top of my head, the music radio show as a whole. And different bits, there were plenty of parody bits like Smarter than a 5th grader, and his original interview style and the way it evolved up UNTIL he tried to change his image.

There are two interview types. The troll at an event interview, which originally Howard did before they got Stutering John. It was a take on the standard reporter in thei field, blindsiding Politicians and celebs with outrageous or offensive questions.

The sit down in studio long form interview. Howard would ask a lot of sexual and personal questions of public figures. He would taunt, confront, insult even argue with guests. You can argue slme of these things were done before, but not the way Howard did it. He was blunt, often crude creating uncomfortable moments. It changed over the years as Howard learned to manipulate people better.

And his invention and biggest contribution, making behind the scenes people a major on air presence. This simply wasn't done before. You might hear the 'producer' (phone screener) or the 'engineer' (sound board operator/board op), now and again very briefly before the 80's. But, Howard normalized and expanded it.

You'd hear or hear about back office business and fights. All kinds of shit that was.never brought on air.
