Vista Breaks Through 30% U.S. Market Share

New York and Dublin, Monday, March 23, 2009: For the first time last week Windows Vista consistently broke 30% share of the operating system market in the United States according to research by StatCounter which provides free website traffic statistics.


"Based on daily data Windows Vista has only topped 30% a few times before and only for a maximum of three days running. This is the first time it has broken through 30% on a weekly basis suggesting that it is gaining some consistent traction in the US," commented Aodhan Cullen, CEO and founder, StatCounter.

However, he said that the data suggested that there was still resistance to Vista in the business market. "The data illustrates clearly that Vista peaks at the weekends while XP peaks during week days."


Cullen added that Mac OS X is gaining market share. Its share of the operating system market has grown 25% from 6.6% in January (week three) to 8.3% last week. Windows XP still leads the market with 56.6% last week down from 70% in January.
