Although it is impossible to be precisely sure, there are several benchmark indicators for estimating the approximate size of the Internet and World Wide Web.  Number of users is the most helpful measure.

For the purposes of convenience, the Internet and the World Wide Web will be considered synonymous for the trend analyses below.

Resources: There are several companies who attempt to measure the Internet's usage: the Internet Society, ClickZ, Vsauce, Internet Live Stats, Gizmodo, Cyberatlas.internet.com, Statmarket.com/Omniture, marketshare.hitslink.com, Nielsen Ratings, Office of the CIA, Mediametrix.com, comScore.com, eMarketer.com, Serverwatch.com, Securityspace.com, internetworldstats.com, and the Computer Industry Almanac.

These groups use custom techniques of polling, electronic tallying of server traffic, web server logging, focus group sampling, and other measurement means.

Here is a compilation of statistical projections from Internet Live Stats:

IV) Conclusion:

Regardless of the accuracy of these statistics, it is safe to conclude that the Internet is a daily tool for millions of people worldwide. When it first started in 1989, the World Wide Web had 50 people sharing web pages. Today, at least 3 billion people use the Web every week as a part of their lives. More countries outside of North America are going online, and there is no stoppage of growth in the foreseeable future.

You might as well get used to the Internet and the World Wide Web as a part of daily life, folks. Over 3 billion other people already do.
