As others pointed out, web, out of CH. Datagrams as an FR invention. Fiber optics, CN

I purposely did not mention the "inventors" of these 3 random tidbits because, guess what? It's not that much important because invention is an iterative process and nationalism should not have any part in it. Don't be glad <country> invented <thing> because they usually didn't, and it was a collective progress made on top of something else.

However, the life of Tim Berners Lee is very interesting, the maths of Pouzin are cool and Kao got a Nobel Prize in physics...
