According to Wikipedia:
Several important achievements in particle physics have been made during experiments at CERN. These include, but are not limited to, the following.
* 1973: The discovery of neutral currents in the Gargamelle bubble chamber.
* 1983: The discovery of W and Z bosons in the UA1 and UA2 experiments.
* 1989: The determination of the number of light neutrino families at the Large Electron Positron Collider (LEP) operating on the Z boson peak.
* 1995: The first creation of antihydrogen atoms in the PS210 experiment.
* 1999: The discovery of direct CP-violation in the NA48 experiment ...
The World Wide Web began as a CERN project called ENQUIRE, initiated by Tim Berners-Lee in 1989 and Robert Cailliau in 1990 ...
That World Wide Web thing worked out pretty well.
