1. Which was invented first, the Web or the Internet?2. We mentioned Vannevar Bush, Doug Engelbart, J.C.R. Licklider and Tim Berners-

Lee in this presentation. Which would you say were visionaries, prototype builders and product invetors?

3. In your own words, what were the contributions of Bush, Engelbart and Berners-Lee?

4. Engelbart knew of Bush’s vision and Berners-Lee knew of Engelbart’s work – how did they learn of each other?

5. Can you think of examples of the sort of sharing and collaboration that dominated the early Internet culture that are still with us today?

6. Why did Berners-Lee make the effort to invent the Web? What was his motivation and reward?

7. What is the economic value of the Web? Is the Web more valuable to individuals, organizations, and society than Wikipedia? Microsoft Office? The Apache Web server program? The Los Angeles freeway system? The Interstate Highway system?

8. How can one evaluate infrastructure like the Web or the Los Angeles freeways? 9. What would have happened to the Web if CERN had decided to copyright and sell

the software and not authorize Berners-Lee to share it freely?
