More interesting analysis of the ramifications of Yahoo’s purchase of Overture:

CNET “Yahoo finds itself in search spotlight”

“Yahoo for now will face off most directly with Google, but analysts said the wild card will likely be Microsoft. MSN is Overture’s biggest partner, delivering as much as one-third of Overture’s revenue this year, or an estimated $350 million. As a result, many industry watchers say that it is only a matter of time before MSN takes stock of its alternatives, including replacing Overture with Google on its Web sites and hastening efforts to build its own Web search technology.”

It will be interesting to watch a three-way fight over the next year or two. But don’t be fooled, new contenders can still rise up from nowhere. Three years ago we wouldn’t have been imagined that Yahoo would be fighting an upstart called Google in a few years.
