WorldWideWeb – the first browser

At CERN, a Swiss research center, a British physicist and internet pioneer Tim Berners-Lee created the world’s first web browser, called WorldWideWeb. The browser was also a simple WYSIWYG (What You See Is What You Get) editor for editing web pages. WorldWideWeb only worked with the NeXTStep operating system. Later, the browser was renamed Nexus to avoid confusion with the World Wide Web (WWW).
