hey europe, I'm sure tools to do side by side comparison / CPA versus CPM versus CPC will come in time (though CPC might vanish after awhile).

It only makes sense. CPM is a useful tool for advertisers in many ways from a branding point of view. CPA makes obvious sense.

Google's huge value proposition is, let's face it, this huge gosh darn database they have on IP addresess and there interestes.

They hit you every which way - gmail, adsense, you tube, google.com .. They have profiled every internet user down to a T. Do you watch videos on how to play a guitar? Then maybe guitar ads are just the thing for you, even if you're on a website about the waterways of venice.

Google's value proposition is their ability to server the right ad at the right time. It only makes sense that we let them do that rather than do it ourselves.

CPA will also allow us to embed ads anywhere anytime. Google doesn't really care where and how we embed them. It's meaningless to them.

Which means ... you guessed it .. software. We can start writing software and putting in ads. This, of course, is the downfall of Microsoft.

This was always on the radar. We always new this was going to happen eventually, and now it has. I'd say it's a brave new world out there, but it's been a brave new world for quite some time now..
