Web navigation
Web navigation came about with the introduction of the World Wide Web, in 1989 when Timothy Berners-Lee invented it. Once the world wide web was available, web navigation increasingly became a major aspect and role in jobs and everyday lives. With one-third of the world’s population now using the internet, web navigation maintains a global use in today's ever evolving international society. Web navigation is not restricted to just computers, either, as mobile phones and tablets have added avenues for access to the ever-growing information on the web today. The most recent wave of technology which has affected web navigation is the introduction and growth of the smartphone. As of January 2014, 58% of American adults owned a smart phone, and that number is on the rise from previous years. Web navigation has evolved from a restricted action, to something that many people across the world now do on a daily basis.
Global brain
Although some of the underlying ideas were already expressed by Nikola Tesla in the late 19th century and were written about by many others before him, the term “global brain” was coined in 1982 by Peter Russell in his book "The Global Brain". How the Internet might be developed to achieve this was set out in 1986. The first peer-reviewed article on the subject was published by Gottfried Mayer-Kress in 1995, while the first algorithms that could turn the world-wide web into a collectively intelligent network were proposed by Francis Heylighen and Johan Bollen in 1996.
