The World Wide Web, the WWW or the Web refers to an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. It was invented by the English scientist Tim Berners-Lee in 1989. He wrote the first web browser computer program in 1990. The World Wide Web has been central to the development of the Information Age and is the primary tool billions of people use to interact on the Internet.
Web pages are primarily text documents formatted and annotated with Hypertext Markup Language (HTML). In addition to formatted text, web pages may contain images, video, audio, and software components that are rendered in the user's web browser as coherent pages of multimedia content. Embedded hyperlinks permit users to navigate between web pages. Multiple web pages with a common domain name make up a website. Website content can largely be provided by the publisher or by users who contribute content online.
Recently, many people have criticized today's misuse of the web. The inventor of the World Wide Web, Tim Berners-Lee himself has warned of the dangers of the Internet. According to him, the web has become a tool in the hand of the powerful to get what they want. For example, he warns that fake news is disseminated either to generate a lot of money or to attempt to manipulate people's opinions . Another worry was the gross invasion of privacy. Tim Berners-Lee is also concerned about governments' misuse of the Internet to collect personal data to manipulate or oppress people.
