According to an interesting article on the American Marketing Association website:
"Search ad spending is now responsible for 40 percent of online ad revenue, and by 2010 it should surpass display advertising, according to JupiterResearch.

"Seven of the ten giants own significant newspaper and magazine assets, and Google and Yahoo! are clearly diverting advertising revenue from them," they report."
This could spell trouble for traditional mainstream publishers. Steve Smith has written an interesting article that merits some review. Read more at the AMA website.
