Given the ease-of-use of most Web client interfaces, and the recent excitement and press surrounding the Web, it's no wonder that its use and presence have grown at such incredible rates. Although it’s very difficult to measure the exact number of Web information services, the Internet has been picking more than one new Web server a day since June - as of December ‘93, over 600 World Wide Web servers on reachable on the Internet. This statistic does not reflect the number of Web servers which are used as internal document distribution servers in many universities and research centers.
The most popular Web client is considered to be NCSA’s Mosaic which is available for X Windows, the Macintosh and now Windows 3.x. PCWeek recently dedicated 4 columns to the public domain Mosaic program for Windows (unfortunately, the screenshot demonstrated a connection to the Novell WWW Internet server...). The NCSA team has well to measure the number of Mosaic downloads via FTP servers which number close to 700,000 by year-end 1993. Considering the software is likely to be distributed by sites not reporting to NCSA and that a number of alternative Web clients are available, it is fair to assume that over 1,000,000 end users have access to the Web, and that this number is growing rapidly. Although available for Windows, the current implementation is considerably weaker than its Unix counterpart.
