Deep Thoughts
As we adjust the definition of what advertising is from saying things to doing things, do charts like these tell us anything of any use?
Most of these charts include some combination of display, search, sponsorships and email. Obviously all valid, but we're also disincluding just about anything remotely interesting that's happening on the web. I'd also take issue with using an "internet" bucket, anyway, but still. Seems like we're tying the entirety of the fate of the digital industry to whether or not we can sell a friggin' banner. No thanks.
On the other hand, your guess is as good as mine on how to measure all the rest of it.
