Since Bing’s debut in July, it continues to gain market share slowly. In August, Bing gained 0.4% of the search market, to achieve 9.3% of total search query volumes in the U.S. In the same month, Google’s market shared dropped by one point to 64.6% while Yahoo’s market share remained unchanged at 19.3%.

In comparison to other major search engines, Bing showed a steady growth of nearly a half-point market share gain every month for the past three months. Bing grew faster than Google for the first time in August, with a 31.9% annual increase in search queries compared to 21.6% growth for Google and 16.8% for Yahoo.

It is worthwhile to mention that while Bing might be growing faster than Google, Google still dominates the U.S. search market with 64.6% and the combine market share of Yahoo! & Bing is only 28.6%.

At the current moment, IE (IE6+IE7+IE8) all together holds only 54.4% of the web browser market which is a 11.4% drop since March, 2009. The majority of that lost market share was captured by Firefox 3.0, which currently has 27.6% market share. While this was occurring, Bing has actually increased market penetration in both the U.S. and around the world.

Since Bing’s debut on June 1st, it received a lot of publicity and fanfare. According to comScore, Bing’s daily searcher penetration had reached to 16.7% between June 8, 2009 – June 12, 2009.
