The author seems to think that there has been "no innovation" in the digital advertising space in 18 years. I'm not so sure I agree with that. I think we've seen numerous innovations. I mean Google built a business around the innovation that was AdWords. There have been other examples like those stupid hover links that block content and text link ads that Google ended up pretty much killing. I agree that these may not be the best things to come but there have been changes. In the mobile space we've seen all kinds of new formats such as dropping and icon on the desktop and push messages (as annoying as they both may be). We've mide strides it's just that no one has really found something that completely replaces banner ads, and then mobile throws a wrench into everything.
