What year was the internet developed?

Answer 1

The first internet like network was probably the ARPANET.

In August 1962 computer scientist J. C. R. Licklider, sent out a memo, discussing the idea of an "Intergalactic Computer Network". The ideas in this memo are still used in todays internet. J. C. R. Licklider went on to work with the Advanced Research Projects Agency (ARPA), a division of the US Department of Defense. He helped with the ideas for what became the ARPA Network or ARPANET. The ARPANET's purpose was to link computer science departments at various universities, to improve the deliver of computing results. The contract for it's construction was given to BBN Technologies on 7 April 1969. ARAPANET's first version was completed within 9 months.

Tim Berners-Lee is often credited for creating the internet. In fact he and his team only created a mark-up language called Hyper-Text Mark-up Language or HTML and the protocol for it's transfer known as Hyper-Text Transfer Protocol or HTTP. HTML was simply a way of creating text documents that can link to other documents. This was called a hyper-link. Other tags were added to HTML through it's development to allow for images, input fields, raster plugins, applets and much more to allow more of the functionality we have in today's websites.

In 1980 Tim Berners-Lee, a physicist at CERN proposed and built a prototype of a system for sharing documents called ENQUIRE. In 1989, Berners-Lee wrote a memorandum proposing an Internet-based hypertext system. He finished a writing a HTML browser in 1990. In November 24, 1995 the first official HTML protocol was published.

So the answer is the ideas for the physical network began in 1962 and were realised in 1969. The ideas for today's de-facto internet document HTML began in 1980 and were made official in 1995.
