CERN did not create the internet. Tim Berners-Lee created the world wide web.

Also keep in mind that there actually existed many predecessors of hypertext systems (EDIT: see https://en.wikipedia.org/w/index.php?title=Timeline_of_hyper... ); just for some reason (let's say because the world wide web was in the right spot at the right time), the world wide web became hugely popular.

The Internet and the Web are not the same thing. The Web is a service that runs on the Internet, just like DNS, E-Mail, and the like. Your cellphone is not a text messaging program.
