1961 1968 research conducted by severalgroups
Goal was to develop connectivity between different
networks Developed packet switching theory
Advanced Research Projects Agency (ARPA)sponsored a project for cooperative networking
UCLA and BBN awarded contract

By 1972 Network expanded to 15 nodes
UCLA, SRI, UCSB, Univ. of Utah, BBN, MIT, RAND,SDC, Harvard, Lincoln Lab, Stanford, UIU(C), CWRU,CMU, NASA/Ames

By 1973
ARPA renamed the Defense Adv. Research ProjectsAgency (DARPA)
First International connection between computers inLondon and Norway
Development of the TCP/IP protocol began
Ethernet standards designed and developed
End of 1973 Over two dozen hosts
Over two thousand users
75% of all traffic was e-mail

1945 Hyperlink term invented Idea by Vannevar Bush to make Microfiche easier to read
1960s Doug Engelbart creates a hypertext system and invents a
mouse Ted Nelson coined the term hypertext in published
paper
1980 While consulting at CERN Tim Berners-Lee writes a
program to allow links between arbitrary nodes Still several different types of systems trying to
communicate

1989 Tim Berners-Lee writes paper HyperText and CERN
1990
Tim gets approval to purchase hardware and write a newprogramming system to allow hypertext communications
Tim begins work on a GUI browser+editor project
Tim coins the term world wide web to define theproject
Tim releases his invention for public use, therebyensuring it will be widespread
2004 Tim receives the Millennium technology prize.

1993 Marc Andreessen and NCSA
develop a graphical user interfacecalled Mosaic for X.
1994 Marc left NCSA
Fellow students and staff left too
Formed the Mosaic Communications
Corporation. Copyright lawsuits filed by NCSA =
name change to Netscape communications and thecreation of Netscape Navigator

In the October 1994 Issue of Wired, Gary Wolfe notes in the article, "The(Second Phase of the) Revolution Has Begun: Don't look now, butProdigy,AOL, and CompuServe are all suddenly obsolete - and Mosaic iswell on its way to becoming the world's standard interface":
When it comes to smashing a paradigm, pleasure is not the most importantthing. It is the only thing. If this sounds wrong, consider Mosaic. Mosaic is thecelebrated graphical "browser" that allows users to travel through the world ofelectronic information using a point-and-click interface. Mosaic's charmingappearance encourages users to load their own documents onto the Net,including color photos, sound bites, video clips, and hypertext "links" to other
documents. By following the links - click, and the linked document appears - youcan travel through the online world along paths of whim and intuition. Mosaic isnot the most direct way to find online information. Nor is it the most powerful. Itis merely the most pleasurable way, and in the 18 months since it was released,Mosaic has incited a rush of excitement and commercial energy unprecedented inthe history of the Net.

Marc Andreessen's realization of Mosaic isbased on the work of Berners-Lee and thehypertext theorists before him and is generally
recognized as the beginning of the web as it isnow known.
Mosaic, the first web browser to win over theNet masses, was released in 1993 and madefreely accessible to the public.
