The Nielsen Corporation recently released its search engine market share numbers for December 2009. Were there any surprises? Let’s look:

Combine Google with AOL (same results) and you can see that their algorithm serves up nearly 70% of all search results online.

Thanks to the folks over at SearchEngineWatch for calling out this newly-issued data.
