The development of the web began in 1989 by British engineer and computer scientist Sir Tim Berners-Lee and his colleague at the centre for European Organisation for Nuclear Research in Geneva. Using concepts from his earlier hypertext systems like ENQUIRE, The team developed a protocol, Hypertext Transfer Protocol (HTTP), which standardized communication between the servers and clients. Their text-based web browser was released to the general public in 1992. The web gained rapid acceptance with the creation of a web browser called mosaic, developed in the USA by Marc Andreessen, Mosaic’s graphical user interface allowed the web to become, by far, the most popular Internet Protocol. Today, the World Wide Web has millions of active users. Presently, Sir Tim Berners-Lee is the Director of the World Wide Web Consortium (W3C).
