Janco in Park City and the IT Productivity Center have just released their March 2009 Browser and Operating System Market Share White Paper.

Janco reports Microsoft’s IE browser market share has stabilized at 72.23 percent versus 69.72 percent in March 2008 and 78.69 percent in March 2007;

Firefox maintains its number two browser position and is used by almost 17.18 percent of all users;

Google, with its Desktop and Chrome offerings, has just under percent of the market; and acceptance of Vista continues to be below Microsoft's expectation.

Victor Janulaitis, the CEO of Janco, said, “The major browser findings of the study are: Microsoft's Internet Explorer’s market share has stabilized, Firefox a strong number 2, and Google’s Chrome is a non-event.” The White Paper has a detailed historical analysis of browser market share since 1997. The findings are supported by data that is provided both graphically and in spreadsheet format.

On the Operating System front, Microsoft's Vista is installed on just under 1 in 5 desktops (19.53 percent) after 27 months since Vista's first release (RC1).

Janulaitis added, "Vista proves that large companies like Microsoft can and do make huge blunders in technology.

Microsoft can no longer count on moving users to new products like Vista as quickly as they want."
