The history and evolution of the internet
1968-1996 TIMELINE

1969-1971 ARPANET

The world's largest network of computer networks got its original name from the U.S. military arm that funded it: Arpanet was for the Advanced Research Projects Agency. Back in 1969 when Arpanet was created, it connected five sites: UCLA, Stanford, UC Santa Barbara, the University of Utah and BBN. In 1983, the U.S. Defense Department spun-off MILNET*, which was the part of Arpanet that carried unclassified military communications. Arpanet was renamed the Internet in 1984, when it linked 1,000 hosts at university and corporate labs.

1991 The first WWW Server

A NeXT Computer was used by Tim Berners-Lee (who pioneered the use of hypertext  for sharing information) as the world's first Web server, and also an early Web browser, WorldWideWeb  in 1990. Berners-Lee introduced it to colleagues at CERN in March 1991. Since then the development of Web browsers has been inseparably intertwined with the development of the Web itself.

2003-2008 Spam

Back in 2003, an estimated 15 billion spam messages were sent over the Internet daily. That means 45% of all e-mail messages were unsolicited pitches for things such as drugs and penny stocks. Those figures seem quaint today, compared to the 164 billion spam messages being sent daily, representing 97% of all e-mail. During the last five years, spam has changed from being annoying to being malicious, with the growth of spam-driven phishing scams.

2000-2008 Domain name Sales

The Internet's Domain Name System was created in 1984 to match complex IP addresses with easy-to-remember names ending in extensions such as .com, .org, .edu, .gov, .mil and country codes including .de for Germany. In 1998, the U.S. Department of Commerce privatized domain name registrations and operations through the creation of the Internet Corporation for Assigned Names and Numbers. Since then, domain name sales have risen nearly 10-fold, but .com remains the most popular domain.
