I assume that significant new business models will emerge in the web-and-beyond-era of music, and advertising seems to have obvious and imminent potential, given it’s position in many of the successful business models on the web, in general.
But, personally, I avoid advertising except in one case. That one case is: I appreciate the gear ads in the magazine Tape Op–there aren’t too many of them, and they are 99% relevant to the topic.
Otherwise, given the opportunity, I’d probably pay a premium “everywhere” to have most or all of the ads removed, e.g., web, TV, radio, magazines, roads, buildings, etc. Generally speaking: there are way too many of them that are way too irrelevant.
I might comment more later on your new post: I am not sure that what you are talking about is really advertising.
