It's official; Bing has stolen users from Google. A Reuters report yesterday states that Microsoft has increased its share of the U.S search market by 1% in July. This may not seem like much compared to Bing's gains last month, but it's actually quite substantial. This month marks the first time that Bing has gone head-to-head with Google.

Now that Bing is the search provider for Yahoo, the last substantial non-Google competition for Bing has fallen. The percent Bing gained this month came directly at the expense of Google, whose share dropped from 78.48 to 77.54% in July. Microsoft now controls a total 20.36% of the U.S search market.

Whatever happens, August is sure to be a very interesting month.
