Have you read the article? The entire piece builds to the conclusion that what you say is wrong - or at least, not as right as many people have thought in the past decade.

I don't entirely agree with it all.. but if you want to disagree with it, argue with it, don't just state your view that happens to go against the article without (I presume) having read it in the first place.

edit: Since the comment I replied to has since been edited, worth noting that what I replied to was just "Just like every other established industry, software is eating the advertising agency. This trend has been clear since the first release of Google AdWords." Not that the later edit contributes much more to the conversation in my opinion... Yes the article didn't prove its claim, but neither have you.
