Terry Semel, CEO of Yahoo, says he believes that the projected growth of Internet Advertising has been underestimated. With areas such as mobile, video and social not factored into the current projections how much room is there to grow?

Semel qualifies this by saying that different forms and better integration would develop quickly. While it's sensible the projections will change based on the improved performance of these advertising areas, to date it is hard to dispute that the industry is far from achieving that and expectations should not be equal to the performance that search advertising provides. Will we be talking about the new wave of video advertising and how great it performs a few years from now? Terry Semel seems to think so. I'm on the wait and see side of the fence based on the development, track record and performance of contextual advertising over the past few years.
