AdSense offers small advertisers powerful geo and topic targeting that is pretty hard to beat.

Big advertisers, too. (In just the past few days, I've seen ads for three major cruise lines on my site.) If Google can give more control to advertisers and clean up "scraper sites" and other dross, the number of mainstream corporate advertisers is bound to increase--especially if using AdSense remains cheaper than using targeted direct mail.
