Navigating Networks Mosaic Netscape Heyday of radio –Duke University of Library Scriptorium and Ad*AccessScriptorium Ad*Access Compare how radio was described and how the Internet is today

Internet The vast network of networks Offer us an unprecedented level of "connectivity" The Internet implies a level of economic, social and cultural transformation on par with other great movements in history The Internet may be as important to the next century as industrial capitalism was to the past hundred years.

Networks Existence Today different networks exist to convey different kinds of things –Physical versus informational goods and services is one way to parse it. Information network is a relatively recent development in the span of human history –It wasn't until the invention of the telegraph that information networks came into their own, separate from physical transportation networks. The newly wired networks closely followed the path of railways. Not until the advent of wireless technologies did information goods begin to follow paths of their own.

The Evolution of Information Networks Informational complexity (bandwidth) Speed of transmission Cost per bit transmitted (see below) Synchronous versus asynchronous Continuous or dynamic versus static Hyperlinked versus linear structure Multimedia (audio, visual, textual) Interpersonal form of transmission –one-to-one / few-to-few (telephone) –few-to-many (broadcasting -- newspapers, radio and television) –one-to-one / one-to-many / many-to-many (Internet)
