Yahoo, Microsoft, and AOL each carved out a little more U.S. search market share in January, but Google still had the biggest piece of the pie, according to a report Wednesday by ComScore.
Yahoo Web sites accounted for 21 percent of the market (up half a percent) compared to the month before, while Microsoft grabbed an 8.5 percent slice (up 0.2 percent), and AOL nabbed 3.9 percent of the market (a 0.1 percent increase).
Google, while still holding the largest slice of the market by far, accounted for 63 percent of the search industry in January, down half a percent.
One interesting observation from Silicon Alley Insider is Yahoo's consecutive five-month run in posting modest monthly gains in U.S. search market share.
In August, for example, Yahoo's market share stood at 19.7 percent, according to SIA. But in the past five months, it has steadily grown, garnering more than a 1 point increase during that time.
