Google has dominated the online search business for years, but recent stats from comScore has revealed that the search giant's share is slipping while its competitors are gaining.

Every month, new search stats are released by comScore and are eagerly pored over by analysts and tech pundits around the world looking to see who has slipped and who has gained. For the average person, this kind of information might not seem all that important, but in a world where even a small percentage point can be equal to millions of dollars for the companies behind the search and investors alike.

In the numbers for March, one of the surprises was that Google slipped by 0.4 percentage points, which saw it drop to 67.1% of the United States' search market. However, in that same loss/gain column Microsoft grew by 0.2 percentage points to 16.9% of the United States' search market, which is up also 0.4 percent from the beginning of the year.

While Bing might get a lot of flack from the tech world, it has in fact seen its market share climb significantly in recent years. In addition, Microsoft provides the underlying technology of Yahoo's search engine, which, interestingly enough, grew by 0.2 percent to a point of 11.8 percent of the United Statess search market. Unfortunately, and according to statements from Yahoo's new CEO Marissa Mayer, the partnership between Yahoo and Microsoft hasn't paid off like both of the companies had hope.

It also should come as no surprise that in February Yahoo announced that they were entering an agreement with Google to place use AdSense and AdMob systems on Yahoo sites.
