On the flip side of this, I ran a startup that absolutely could not have existed without targeted Web advertising. Our first product was an add-in for collaborating on PowerPoint presentations, and we were able to economically target ads towards people who were actually searching for "PowerPoint collaboration" or similar keywords. I don't see how we could have found those people, or they could have found us, in a more effective or direct way.
