It's true (although it was broadcasted uncrypted) but with YouTube, Netflix or ... the internet in general it's hard to think someone really has no idea what/who Seinfeld is.
I didn't remember it was broadcasted uncrypted. Maybe it was airing too late for 10yo me ? By the way, while everyone here in France know Friends or How I met Your Mother, despite being available on Netflix i'm not sure way more people know Seinfeld nowadays than in the 90s. One must admit it's pretty hard to get into it 30 years after as it aged a little and it never got it primes here.
