The World Wide Web (WWW) has evolved over time from static pages of information (Web 1.0) to user-generated content and social interaction (Web 2.0), and is moving toward artificial intelligence and personalized content (Web 3.0). Key people in the evolution of the web include Tim Berners-Lee, who created the World Wide Web, and John Markoff, who coined the term "Web 3.0". The core technologies that power the web are HTML, HTTP, URLs, and domains.
