The term "Smooth Jazz" actually came about when WNUA was doing a research project and a listener described the music they were playing as "Smooth Jazz."
Station positioners often come out of perceptual research. In this case, the project was a series of one-on-one's conducted by Broadcast Architecture's Owen Leach, one of the best interviewers I've ever known. In fact, it was Leach who determined that radio should not use focus groups but, instead, individual in dept interviews.
In reviewing the videos of the interviews, the listener-originated "smooth jazz" jumped out as a clear listener-relatable description and a viable positioner, particularly since licencing issues with Westinghouse made the use of The Wave a non-option.
When NAC/PAC evolved into Smooth Jazz
NAC and PAC were internal names or descriptors for the format. "Smooth Jazz" is a listener focused term. The former are for a column in R&R, the other is for on air use.
...There's really no rational reason..just because the people who created and syndicated the format decided that was the way to go - and so it was.
Actually, the format was first syndicated by BA and Westinghouse just a little after the intial success of KTWV, and the research was nothing more than the ongoing testing of the format against the regular listeners of the format.
(I'm sure they would say their research backed that decision but you can always create a study to back the decision you have already decided to make...)
Since a music test is not a perceptual project, but, rather a "voting" on each of hundreds and hundreds of possible songs, unless the recruit is totally messed up, the results are quite reliable.
Pre-consolidation, NAC and AAA were the true Adult Alternatives..formats that featured music for grownups who wanted to hear new music (and types of music) created by and for adults..
Mass adult audiences tend to want a large dose of familiar music and a tiny dose of new songs. Smooth jazz simply moved along with the preferences of the listeners until the format aged to the point that sales were impacted.
Both these formats were stripped of almost all of the elements that made them exciting when consolidation happened and corporate owners believed that after you turned 30 you not only didn't want to hear new music and artists, but you were downright afraid of anything beyond the "songs you grew up with."
Consolidation has really nothing to do with the format, as program directors program and the listeners determine the music and direction of it... not "corporations."
