Internet
The Internet is a method of exchanging information with computers through packet switching. The modern form of Internet, known as World Wide Web, was invented by Tim Berners Lee and Robert Cailliau.
Previously, the ancestor of Internet, called Arpanet, was used by the US Military as a method of communication during times of war. It was important to maintain a level of communication from coast to coast, should the Soviet Union attack using nuclear weapons on the mainland.
While initially an innovation for communication, Internet has evolved under a marketing perspective, starting with the dot com boon in 2000 and the lowered prices for fast connections, which are made available to much of a country's population (see also: digital divide). Marketing has influenced the development of web 2.0, with the fast generation of content and attempts at monetizing it.
