Dr. Eric Clemons from the Wharton School of Business is absolutely correct in his observations of push and unwarrented intrusive advertising.
However he misses the central point which is synchronicity and contextuality of content. With rudimentary geo-positioning functionality and profiling, the whole concept of advertising will gradually morph into content relevance. In many ways similar to good old James Bond movies promoting in- movie branding, so our reading contextualization will sharpen ads. The only issue remaining is monitization of non paying ads and I believe Pricerunner.com has solved this to the satisfaction of readers. Not rocket science!
