Bing remains engaged in a serious battle with Google. And there's some new research indicating that Microsoft's search engine is making a bit of headway -- both in terms of market share and new innovative features.

Bing accounted for 25.27 percent of U.S. Internet searches for the four week period ended November 27th, up two percent from October, according to Experian Hitwise. (The numbers include the integration of Yahoo, but even separately both Yahoo and Bing showed some growth). Google remains on top with 70.1 percent of searches, but it showed a small one percent drop.

A separate study released yesterday by comScore showed that Bing gained 0.3 percent during the month of October, while Google and Yahoo showed slight declines. It found that Google controlled 66.2 percent of the search market, while Microsoft owned 11.8 percent (not including integration with Yahoo).

Microsoft can't claim victory yet, but it does show a positive trendline for Bing. And yesterday at the Bing Summit Microsoft Senior Vice President of Research and Development Satya Nadella touted the comScore results and noted that the search engine has grown 48 percent since its launch in June 2009.

Meanwhile, Bing continues to roll out new features, including a new panorama view and mapping services for mobile devices as seen in the video from CNET below. Microsoft's Bing also is bolstering its partnership with Facebook, pointing out links in search results which have been "liked" by Facebook friends.
