Microsoft's Browser Market Share Erodes Over 9.5%

The Browser and Operating System Market Share White Paper has just been released by Janco Associates..

Park City, UT – Janco and the IT Productivity Center have just released its Browser and Operating System Market Share White Paper. The major findings are that in the last 12 months Microsoft’s browser market share has eroded by over 9.5%; Firefox maintained its number 2 browser position with an increase of 5.6% in the same period; Google Desktop is gaining market share; and Netscape version 8 is dead. New in this white paper are recommendations on which browsers to use and not use. A summary of Janco’s browser market share data can be found on the Janco’s web site (http://www.e-janco.com/browser.htm) and the IT Productivity Center’s (ITPC) web site (http://www.itproductivity.org/browser.htm). In addition the full white paper with excel spread sheets can be purchased at both sites for $249.

Microsoft Browser Market Share History

The top five browser market share rankings are: 1 - Microsoft’s IE – 63.86%; 2 - Firefox – 17.40%; 3 – Netscape – 10.21%%; 4 – Google Desktop – 2.38%; 5 – Mozilla – 1.40%. The CEO of Janco Associates, Inc and the ITPC, M. Victor Janulaitis said: “The positive glow on Firefox was dulled in with the identification of some security gaps in Firefox. But the real story is the erosion of Microsoft’s market share.” He added, “Netscape’s release of version 8 has become a non-player.”
