Growth of the Internet
Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] Preliminary version, July 6, 2001 Abstract The Internet is the main cause of the recent explosion of activity in optical fiber telecommunica- tions. The high growth rates observed on the Internet, and the popular perception that growth rates were even higher, led to an upsurge in research, development, and investment in telecommunications. The telecom crash of 2000 occurred when investors realized that transmission capacity in place and under construction greatly exceeded actual traffic demand. This chapter discusses the growth of the Internet and compares it with that of other communication services. Internet traffic is growing, approximately doubling each year. There are reasonable arguments that it will continue to grow at this rate for the rest of this decade. If this happens, then in a few years, we may have a rough balance between supply and demand. Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] 1. Introduction Optical fiber communications was initially developed for the voice phone system. The feverish level of activity that we have experienced since the late 1990s, though, was caused primarily by the rapidly rising demand for Internet connectivity. The Internet has been growing at unprecedented rates. Moreover, because it is versatile and penetrates deeply into the economy, it is affecting all of society, and therefore has attracted inordinate amounts of public attention. The aim of this chapter is to summarize the current state of knowledge about the growth rates of the Internet, with special attention paid to the implications for fiber optic transmission. -

Visions of Electric Media Electric of Visions
TELEVISUAL CULTURE Roberts Visions of Electric Media Ivy Roberts Visions of Electric Media Television in the Victorian and Machine Ages Visions of Electric Media Televisual Culture Televisual culture encompasses and crosses all aspects of television – past, current and future – from its experiential dimensions to its aesthetic strategies, from its technological developments to its crossmedial extensions. The ‘televisual’ names a condition of transformation that is altering the coordinates through which we understand, theorize, intervene, and challenge contemporary media culture. Shifts in production practices, consumption circuits, technologies of distribution and access, and the aesthetic qualities of televisual texts foreground the dynamic place of television in the contemporary media landscape. They demand that we revisit concepts such as liveness, media event, audiences and broadcasting, but also that we theorize new concepts to meet the rapidly changing conditions of the televisual. The series aims at seriously analyzing both the contemporary specificity of the televisual and the challenges uncovered by new developments in technology and theory in an age in which digitization and convergence are redrawing the boundaries of media.

DRAWING the COLOR LINE, by Howard Zinn
"Columbus, The Indians, and Human Progress" - Chapter 1 from Howard Zinn's A People's History of the United States : 1492 - Present, Revised and Updated Edition, (New York: HarperCollins, 1995) - by permission Arawak men and women, naked, tawny, and full of wonder, emerged from their villages onto the island's beaches and swam out to get a closer look at the strange big boat. When Columbus and his sailors came ashore, carrying swords, speaking oddly, the Arawaks ran to greet them, brought them food, water, gifts. He later wrote of this in his log: They...brought us parrots and balls of cotton and spears and many other things, which they exchanged for the glass beads and hawks' bells. They willingly traded everything they owned...They were well-built, with good bodies and handsome features....They do not bear arms, and do not know them, for I showed them a sword, they took it by the edge and cut themselves out of ignorance. They have no iron. Their spears are made of cane...They would make fine servants....With fifty men we could subjugate them all and make them do whatever we want. These Arawaks of the Bahama Islands were much like Indians on the mainland, who were remarkable (European observers were to say again and again) for their hospitality, their belief in sharing. These traits did not stand out in the Europe of the Renaissance, dominated as it was by the religion of popes, the government of kings, the frenzy for money that maked Western civilization and its first messenger to the Americas, Christopher Columbus. -
Funny Noises by Marshall G
Funny Noises by Marshall G. Emm N1FN/VK5FN [email protected] [First published in "The Low Down" February 1999] The Mother of All Network Protocols I recently had the pleasure of reading a book called The Victorian Internet, by Tom Standage1. It’s not my intention to review it here, but it gave me a lot to think about and is well worth reading. It’s an enjoyable history of telegraphs and telegraphy, but its true value is in providing a perspective for viewing today’s developments in communications. The basic premise of the book is that the “mother of all networks” was the telegraph network which began before the Civil War and continued to develop into the 1920's. Standage sees the telegraph network as a model for the Internet and there are indeed many similarities. The Internet is often cast as a revolutionary mode of communication, with far-reaching social, political, economic, and moral implications. But if you look at it as a logical extension of technology, the Internet is evolutionary rather than revolutionary. In contrast, the introduction of the electric telegraph was truly revolutionary. That word “electric” is very important, because the first telegraph system was demonstrated in France in 1794, and the french gave it the name “telegraph.” But it used moving signal arms and was limited to line of sight between stations, hence really just an improvement on smoke signals and beacon fires. It took another fifty years of development before the electric telegraph came into being, but once it did the development of true networks was immediate, explosive, and with far-reaching consequences. -

(Humanist.Com) Review of Writing on the Wall: Social Media—The First 2,000 Years by Tom Standage
Howard Schneider’s (humanist.com) Review of Writing on the Wall: Social Media—The First 2,000 Years by Tom Standage. Tom Standage’s self-imposed mandate is to assuage our technoterror. In books like his laudable study of the telegraph, The Victorian Internet (1998), and An Edible History of Humanity (2009), the author demonstrated, mostly successfully, that technology is liberating and good for us. In his new book, Standage confronts one of the major generators of modern technology anxiety: digital social media. Writing on the Wall, like all of Standage’s books, is a fine work. It’s well written and researched, and contains, as usual, the author’s dry wit. But I’m not sure that he fulfills his agenda this time. One thesis of this book, that social media—information dissemination through social networks—have been with us for at least a couple of millennia, gives Standage the opportunity to do something he does superbly: scrutinize the past to show how it links to and influences the present. I can only touch on some of the historical moments he examines. Standage begins in the waning days of the Roman Republic, in the first century BCE. The Romans created “the first social-media ecosystem,” he says, a system that allowed patricians to exchange political news and gossip (some things don’t change). The engine that made this communications network viable was slavery: slaves served as scribes and as messengers, in the republic and throughout its distant provinces. The letters disseminated through this system were often considered, by senders and recipients, to be meant for perusal by many besides the addressees. -

Afterword: Omissions,Additions, and Corrections The astute reader will notice that I’ve omitted a few online services. Some were so short-lived or of so little consequence that they would be meaningless to most readers. Others are beyond the theme or time frame of this book. Some of the omissions: ABI/INFORM (Abstracted Business Information), a database of abstracted information from selected business publications, hosted by ORBIT, Dialog, and eventually UMI/ProQuest Data Courier, a small online service hosted by the Louisville Courier- Journal (the owners of which bought ABI/INFORM under the company name “Data Courier”) EasyLink, Western Union’s now-defunct email/FAX/mail system Easynet, a front end for more than 700 database services EasyPlex, a specialized CompuServe email service E-COM, the United States Postal Service’s electronic messaging service (EMS) Freenet, free BBSs in cities such as Cleveland and Rochester that used the same software and were designed to serve as community centers Info-Look, a gateway to online services hosted by Nynex Internet Relay Chat (IRC), the first implementation of real-time chatting via the Internet (Jarkko Oikarinen, 1988) Knowledge Index (KI), a subset of Dialog databases The Microsoft Network (MSN), more an ISP than online service that started after Bill Gates decided that the Internet was going to be important, after all 177 178 Afterword MIX, the McGraw-Hill Information Exchange, a CoSy-based service for educators NABU Network, a Canadian online service that operated
