History of the World Wide Web
1980–1991: Invention and implementation
While inventing and working on setting up the Web, Berners-Lee spent most of his working hours in Building 31 (second floor) at CERN (46°13′57″N 6°02′42″E﻿ / ﻿46.2325°N 6.0450°E﻿ / 46.2325; 6.0450﻿ (CERN Building 31, Birthplace of the World Wide Web)), but also at his two homes, one in France, one in Switzerland. In January 1991 the first Web servers outside CERN itself were switched on.
