ComScore Networks' monthly analysis found that in the last month of 2006 (that's December for all North Americans still half asleep) Google not only continued to dominate the search engine market, but improved gained market share. Google had 47.4% of the US search market, an increase of 0.4% over November 2006. Yahoo also progressed, by 0.3%, and captured 28.5% of the market.
The article refers to MSN-Microsoft but I’ll assume that includes Windows Live Search. Regardless, it Microsoft did not grow. The software giant took 10.5%, Ask (without Jeeves) took 5.4% and Time Warner (AOL) grabbed 4.9%. Americans searched 1% more than the previous month, aka 6.7 billion searches.
