In Europe?
"Mosaic was developed at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana–Champaign beginning in late 1992." -- Wikipedia
Other than Linux's European origin, Europe has not produced any viable operating system or browser. It continues to rely on key software of American origin, like the rest of the world.
The Brit Tim Berners-Lee designed the architecture, wrote the first browser and web server, and wrote the first HTML spec at CERN around 1989. Mosaic was released in like 1993 after Berners-Lee released his specs and source.
To claim the internet was invented in Europe is equally absurd.
Internet created 1983. WWW created 1989.
The internet was created by meshing many different networks together (mostly ARPANET and SFNET).
Networks which now form the backbone of the internet also existed in europe at the time, mainly in britain and france.
