Web traffic analytics firm Hitwise reports that in January, Google’s measured market share dropped about one percent from December. Since Microsoft’s Bing search engine — sorry, discovery engine — launched in June of 2009, Google’s gradual absorption of the entire search engine market has stalled, fluttering in place at around 71 percent.

Bing, says Hitwise, is likewise stalled at around nine percent. Microsoft’s pretty-picture machine took traffic away from Yahoo and other non-Google sites last year. Yahoo cut a deal with Microsoft to let Bing handle Yahoo search requests, but I’m sure Microsoft would prefer to get that traffic direct to Bing.

Hitwise provided me with the data for this chart.
