Yahoo dumps Google. They're powered by their own search engine now, thanks to the acquisitions the made last year. It's amusing to see how the browser wars have turned out. In the very beginning, we had the following players:

Altavista - One time leader in the websearch engine. Commited harakiri by tranforming into a portal, among other things.
AllTheWeb - Indexes a LOT of pages. I used it for pages I couldn't find anywhere else. But that's about all I used it for.
Yahoo - Search, mostly dependent on the then-huge human-managed directory. Plus points: search quality, and portal features.
Google - straightforward, intuitive and gave the users what they wanted. This simplicity was what people wanted, and hence it became an instant hit with everyone on the internet. Both its popularity and the enourmous intellectual capital it possesses make Google a prospective Microsoft or IBM.
Overture - the company that created the notion of sponsored links. While we know that Google is now a popular choice for keyword based ad targetting, Overture is definitely the superior being when it comes to ads.

So till last year, we had Google as the undisputed leader, with Yahoo, AllTheWeb, Altavista all trying to do something about the monopoly. Then, in a seemingly comical turn of business maneuvures, Overture bought Altavista and AllTheWeb. And Yahoo in turn, bought Overture. Thus we now have a hierarchy of 4 search companies, forming a force that's probably large enough to reckon with Google. This reminds me of the coalition governments that we have in India. So can Google survive this attack and maintain it's lead? Let's see what happens.
