PresenterNet, provider of online interactive Web presentation services, today announced survey evidence identifying Firefox and Macintosh as key enablers to Web Conferencing success. Through user surveys, analysis of system logs, and interviews of corporate customers, the company found that the population of users and audience members not using Windows or Internet Explorer represents a critical success factor. The company has published this data in a report entitled, “Survey of Web Conferencing User Requirements and Preferences.” PresenterNet CEO Doug Wolfgram explained stating, “The data tells us that virtually all presenters need a system that supports both Macintosh and Windows platforms. It is also very clear that support of Microsoft Internet Explorer is not enough. Firefox support is now mandatory.”
