- MIDS Press Release: New Data on the Size of the Internet and the Matrix
-
- How many people use the Internet? Businesses make decisions based on
- answers to this question, and governments decide programs on them.
-
- The survey.
-
- Starting 15 October 1994, Matrix Information and Directory Services and
- Texas Internet Consulting sent survey questionnaires by electronic mail
- to most of the domains representing organizations on the Internet, and
- we tabulated responses received through 15 December 1994. We received
- 1468 usable responses and used them to estimate the sizes of the
- Internet and the Matrix as of October 1994.
-
- These are estimates, not exact and definitive figures. However, they
- are based on a large sample of the organizations (companies, universities,
- governmental agencies, individuals, etc.) on the Internet. Comparing
- the domain names of the responses with those of the original survey
- list, we calculate a confidence interval of about 38 percent. These
- are the only estimates of the size of the Internet that, so far as we
- know, have associated any confidence interval at all.
-
- The estimates.
-
- Different people mean different things when they refer to the Internet.
- To avoid confusion, we provide definitions along with our estimates.
-
- For the Core Internet, we estimate 7,800,000 users (people) of 278,000
- computers that can *provide* interactive services such as TELNET
- (remote login), FTP (file transfer) or WWW (hypertext), as of October 1994.
-
- For the Consumer Internet, we estimate 13.5 million users of 389,000
- computers that can *use* the interactive services supplied by the core
- Internet, for example people who can use Mosaic or Lynx to browse the
- World Wide Web, as of October 1994.
-
- For the Matrix, we estimate 27.5 million users who can exchange electronic
- mail with other users in the Matrix, as of October 1994.
-
- The Internet and the Matrix.
-
- These categories fit inside each other: the Matrix includes the Consumer
- Internet, which includes the Core Internet.
-
- ``It's like those Russian dolls,'' said John S. Quarterman, editor of
- Matrix News and Matrix Maps Quarterly, ``where you open up Yeltsin and
- find Gorbachev, and inside Gorbachev is Brezhnev.''
-
- To find which category fits you, apply these simple tests:
-
- If you can send mail to an address in the Matrix, such as mids@tic.com,
- you're in the Matrix.
-
- If you can connect with FTP to ftp.ripe.net, or use Mosaic or Lynx
- to reach http://www.ripe.net, you are in the Consumer Internet.
-
- If your computer runs an FTP, TELNET, Gopher, WWW, or other interactive
- server that users outside your own organization (your company, university,
- etc.) can use, then you're in the Core Internet.
-
- The most important distinction is between the Matrix and the Internet.
- Mail is the simplest and most widely used network service, both on the
- Internet and on other networks. But it is not the distinctive
- characteristic of the Internet, since most other networks have it,
- too. The Internet's interactive services, supported by its TCP/IP
- protocols, are what distinguish it from other networks. You can access
- many of those services by mail, even including FTP, Gopher, and WWW,
- but that's a completely different level of convenience, speed, and
- utility than using them interactively over the Internet itself.
-
- ``WWW by mail is like shopping by mail order catalog,''
- said Quarterman, ``while the Internet is like a big shopping mall.''
-
- Where other networks fit.
-
- What about UUCP, FidoNet, WWIVnet, and BITNET? They're all
- in the Matrix. These networks are not part of the Internet,
- although some of their hosts are. We counted their users in
- our estimate of the size of the Matrix.
-
- What about Prodigy, CompuServe, Nifty-Serve, PC-VAN, AT&T Mail, GEnie,
- Sprint-Mail, Easy-Link, MCI Mail, and Tymnet? Those ten systems (and
- quite a few others like them) are all in the Matrix, but not yet on the
- Internet. We have counted the users of these systems in our estimate
- for the Matrix. Some of them are moving towards letting their users
- use interactive Internet services, and when they do, we will start
- counting those that do as part of the Consumer Internet.
-
- A few similar centralized systems, such as AOL, Delphi, and BIX, already
- let their users use interactive Internet services, and are therefore
- on the Internet, and we counted their users in our Consumer Internet
- user estimate. Some of these three systems may actually be in the
- Core Internet, but until we're sure we are counting them as being
- in the Consumer Internet.
-
- Growth and dates.
-
- The exact size of the Internet can only be estimated, but one thing
- that is known for sure by many different measurements is that the
- Internet is growing exponentially, approximately doubling in size each
- year, and has been doing so for at least the past six years now. Each
- year there are as many new people on the Internet as all the people on
- the Internet the year before. That's why it is important to cite a
- date for any estimate of the size of the Internet. Our estimates here
- are for October 1994.
-
- ``Here today, lots more tomorrow.'' said Quarterman, ``We'll
- be measuring it as it grows.''
