I think the fact that most of us here were either in the business or many of our registered users have a real interest in the workings of radio and tv sort of cancels most of us out as to how accurate this survey is.  We are not the best ones to judge whether people listen or not to commercials since we are not the average listener. We listen to radio much closer than the average person and are more critical in most cases. Some people still use radio for background or ambience especially music.

In the car I flip around the dial constantly, but when I am with non radio friends or family members and they are in charge of the radio, they almost never change the station. Real listeners have more loyalty to their station(s) and tend to stick with them over much longer periods of time. In terms of talk, they seem to be more influenced by the topic, host and guests rather than the number of commercials on a show or station. If the topic is not of interest, they could check out the other talk stations but often come back eventually to their main station, for a newscast or the next topic or host.   

Age would be a factor as well, I am sure younger people, assuming they are even listening to radio, would flip around more, at least in the car.  As we supposedly mature and lose some of our youthful energy and have a better idea of what we like and don't like to listen to would cut down on station flipping.

In my humble opinion, I have noticed there is a difference to what we in the industry think is important and what many listeners feel is important. To all the cancon haters, my experience is that to most average listeners whether we play 30-35% cancon is not a big deal to them.

They may complain about repetition of songs and artists and many in the industry assume it is cancon, but usually it isn't. I had the opportunity to do a deeper dive on this and most listener complaints  were regarding the type of music and not specific artists. Some artists and songs were mentioned for overplay and almost none were Canadian or cancon.
 
It only becomes an issue if it is pointed out or centered out to to the listener, but that also applies to commercials, other music and artists or particular hosts.  So I viewed this as leading questions which can inadvertently  direct the survey which doesn't help with accuracy. Sort of like making an issue of something that didn't exist for the listener in the first place.

And in this information there were complaints about too many commercials but those complaints tended to be on talk shows.  Sometimes hosts would not follow the breaks close enough or not get to the topic or guest quickly and we would be forced to double up on commercial breaks which sounded like crap.  So this was more of an issue of the host getting off topic and wasting air time with chit chat, and this is easily corrected.

So all I am saying is that the survey could very well be accurate. Our industry lives and dies by revenue and results for advertisers, so anything to counter the lazy attitude of  "nobody listens to radio or commercials" is important.  The fact that the survey was measured by PPM also gives it credibility as well.

It's very simple. If I hear too many ads I look for the competition and shop there. 
Yes, this means that an ad for the Brick means I ALSO do not shop at Leon's.
However, sometimes this method of thinking can easily forget who owns what.
