The Internet Portal
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobilecomputers were connected to the network. Although the Internet was widely used by academia in the 1980s, commercialization incorporated its services and technologies into virtually every aspect of modern life.
Most traditional communication media, including telephony, radio, television, paper mail and newspapers are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, and video streaming websites. Newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking services. Online shopping has grown exponentially for major retailers, small businesses, and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online. Business-to-business and financial services on the Internet affect supply chains across entire industries.
The Internet has no single centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own policies. The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Todays list of New Seven Wonders. ('Full article...)

"On the Internet, nobody knows you're a dog" is an adage which began as the caption of a famous cartoon published by The New Yorker on 5 July 1993, and authored by Peter Steiner. The cartoon shows two dogs: One sitting on a chair in front of a computer, speaking the caption to a second dog sitting on the floor. As of 2000, the panel was the most reproduced cartoon from The New Yorker, and Steiner had earned over $50,000 (USD) from the reprinting of the cartoon.

Webcams are small cameras, (usually, though not always, video cameras) whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion.

Selected biography
Chad Meredith Hurley (born 1977) is co-founder and Chief Executive Officer of the popular San Bruno, California-based video sharing website YouTube, one of the biggest providers of videos on the Internet. In June 2006, he was voted 28th on Business 2.0's "50 people who matter" list. In October 2006 he sold YouTube for $1.65 billion to Google. Hurley worked in eBay's PayPal division before starting YouTube with fellow PayPal colleagues Steve Chen and Jawed Karim. One of his tasks at eBay involved designing the original PayPal logo. Newsweek describes Hurley as a user interface expert. He was primarily responsible for the tagging and video sharing aspects of YouTube. YouTube was born when the founders (Hurley, Chen, and Karim) wanted to share some videos from a dinner party with friends in San Francisco in January 2005. Sending the clips around by e-mail was a bust: The e-mails kept getting rejected because they were so big. Posting the videos online was a headache, too. So they got to work to design something simpler. In 11 months the site became one of the most popular sites on the Internet because the founders designed it so people can post almost anything they like on YouTube in minutes.
