One of the things that Storz believed in was moving away from the block program model, which had served radio in the pre-TV era but which had been pre-empted by the new medium. Storz saw TV coming, and it was no coincidence that his move at KOWH was in part a reaction to the prospects of the lifting of the TV freeze "soon".
When I met with him I was on my way to Ecuador where I would build South America's first Top 40 station. I had a long layover in Miami, and visited WQAM where the manager, intrigued by an 18-year-old with a radio station, introduced me to Mr. Storz who was visiting the station. Storz took several hours to instruct me in how to do the format right. A key element was not breaking the format ever and doing everything that was not music as briefly as possible so that the promise of music was always perceived to be immediate.
I think some just imitated the success of the Storz stations. Others became true believers and enhanced the format in their own way, such as Chuck Blore's creation of KFWB.
As I think back, I do not believe that playing "rock n' roll" was a concern to him. I believe he always referred to "the hits" in reference to the music, not to the genre. In other words, if it was a big song, you played it.
