As The World Wide Web Turns 20, Take A Look At The World's First Website. The World Wide Web turned 20 years old on Tuesday. On April 30, 1993, the Web went public for everyone to use (for free) and two decades late CERN, the organization that brought us the Web, has brought the first website back to life at its original address.
