I didn't pick contemporary names because the closer you get to today, the less likely you are to know such names unless you are specifically interested into their specific field. You can look them up, though.

No doubt American universities are not less prestigious, but to think that nothing of relevance happens outside of the US, well... You might have heard of CERN at least. ;)

I think another factor is that the admission system is different. I only know about Germany, but you don't have to apply in the same way at a university and your grades from school are what matters there isn't some additional test like GRE or SAT. So it plays less of a role culturally and has thus less opportunity to be a topic at all in shows and movies even if Americans were to drown in European media.

* edit: on second thought i suppose I am not adequately equipped to talk about global brand awareness as it originally stated. Curious how other countries see collegiate prestige outside of their own or if US colleges have some extra factor?
