Just about now, at 14:00, CERN and probably some more institutions and people are celebrating the 20th birthday of what is known as the WorldWideWeb these days.
In March 1989 Tim Berners-Lee handed in his first proposal for what was the basis of the WWW to his bosses at CERN.
The whole story can be found here and the original proposal is linked here.
Happy Birthday!
And thanks Mr. Berners-Lee.
