Netscape’s Navigator web browser has increased its lead over Microsoft’s Internet Explorer as the primary browser in use in the enterprise, Zona Research Inc has found. The study, which was based on surveys of 113 enterprises, discovered that 60% of respondents used Navigator as their primary means of accessing the web. Only 40% now use Internet Explorer. Compared with the last study, conducted in July (CI No 3,452), Netscape has increased its lead by six percentage points. For the first time since Zona began conducting the survey in 1996, no respondent named any browser other than Navigator or IE. On the figures, Microsoft’s jump in market share from 2% to 40% has come primarily from forcing all smaller players off the field, and only secondarily from the 11% it has shaved off Netscape since figures began to be kept.
