Top Search Engines

According to Comscore Networks and this article, Google is still the top with an increasing share over the previous month. Yahoo lost a little but stayed a strong number 2.

Google 37.3%
Yahoo 29.7%
MSN 15.8%
Time Warner 9.6%
Ask Jeeves 6%

I didn't realize that Time Warner had a search engine, but now I see that this is really AOL. Who owns who there?

Is this a bit of "new math"? The article states that:

Google Inc. remained the search-engine leader in August, accounting for close to 1 in 4 searches on the Web, a Web metrics firm said Monday.

But, I think that a 37% share would be more than 1 in 3. Maybe I am missing something, or maybe this journalist went to a different school than I did.
