When did the World Wide Web start?

The World Wide Web was invented in 1989 by Tim Berners-Lee. Its creation came approximately 20 years after the Internet was developed. The World Wide Web initially served as a way for scientists around the world to more easily share data from experiments.

In October 1990, Berners-Lee established three core technologies still in use as of 2015: HyperText Markup Language, Uniform Resource Identifier and Hypertext Transfer Protocol. HTML is responsible for the formatting of various Web documents and resources, as well as linking to them. URI allows each Web resource to have a unique identifier, while HTTP governs the ability to retrieve linked information.
