What was invented in CERN was hypertext. WWW and internet was largely built and commercialized in US.

I think it’s fair to say that a lot of innovative technologies were invented in Europe, but most of them end up being commercialized in US due to market incentives and the whole funding and support infrastructure these incentives created.

By "inventing the WWW" I meant designing HTTP and HTML as well as implementing the browser and the server software. This all was done by Berners-Lee around 1990.
