A week after Bing’s launch, ComScore says Microsoft’s (MSFT) search market share has already seen “a substantial improvement.”
Microsoft Sites increased its average daily penetration among U.S. searchers from 13.8 per cent during the period of May 26-30 to 15.5 per cent during the period of June 2-6, 2009, an indication that the search engine is reaching more people than before. Microsoft’s share of search result pages in the U.S., a proxy for overall search intensity, increased from 9.1 per cent to 11.1 per cent during the same time frame.

Microsoft is said to be spending somewhere between $80 million and $100 million on Bing’s launch.
