\tangent Google is commited to increasing revenue, but I loved their early idea, of showing you relevant ads that you would <i>want</i> to see. Similar enough to goto.com/overture's idea, of search <i>purely</i> for ads. You're far more likely to pay attention, to click, to buy. And it's sustainable indefinitely because net-better for the world.<p>Although, judging from advertising in general, it may be better for advertisers to get your attention whether you want it or not. And they are the ones who decide whether the advertising occurs.<p>But if another company did ad-relevance better than Google, more efficiently (cheaper) and effectively (clicks, sales), it seems that Google couldn't beat them, because the revenue at first would be lower and Google is Wall St-committed to increasing revenues. They would have to acquire the new company (if they could).<p>Unfortunately, ad-relevance requires data about the person, and Google is best placed for this (alongside Facebook). Despite the privacy-backlash, people increasingly live online and accept the loss of privacy. So, instead, we have startups with new ways to gather new personal data, and are acquired by Google/Facebook.
