For the 8th Week in a Row, Microsoft IE Snags Over 60% in Browser War

Park City, UT, - In an interview today, M. Victor Janulaitis discussed the latest results of an extensive ongoing study, The Internet Browser War. In this study, he found that Microsoft’s Internet Explorer browsers (versions 2 through 5) were used in 60.54% of all internet sessions versus Netscape’s browsers (versions 2, 3, and 4), which garnered only 35.12% during the week ending June 19,1999.  

The data in the study covers a 21-month period from September 9, 1997 through June 19,1999 including over 2,000,000 Internet session data points. The data shows usage of Microsoft’s IE has remained consistent in recent months, reaching as high as 66.61%. Since the survey began, Netscape has lost over 8 points in market share.

Mr. Janulaitis said, “Based on analysis of recent data, it is clear that Microsoft’s IE product is clearly in the dominant position in market share and is not going to relinquish that position in the near future. Anyone designing web sites should definitely take notice”.

Summary graphs from the study are available at Browser Study. In addition the full study can be purchased electronically for $299.
