Google ended the year with 63.5 percent market share versus 58.5 percent in January 2008.
The chart above tells a better story. It comes from the comScore 2008 Digital Year In Review, and shows the share of raw number of search queries in the U.S captured by the five major search engines. All the competitors are flatlining, except Google’s (the purple one). Of the 137 billion estimated total searches performed in the U.S. last year, 85 billion were done on Google.
Ninety percent of all growth in search volume was captured by Google. The increase came mostly from increases in individual searches per person, rather than bringing more people to Google.
