Why has the BBC never shown hilarious sitcom "Seinfeld" on primetime TV? It's far superior to anything we Brits have ever produced (with the exception of Black Books and early Only Fools and Horses).
Seinfeld - one of my favourite ever sitcoms.
But, in answer to your question - Seinfeld was shown on BBC2 a while back I think. I remember watching "The Finale, Part 2" on terestrial TV. And, like I said, I think it was BBC2.
Just watch it on The Paramount Comedy channel when it returns to schedule in September. Or, if you don't recieve Sky or the PCC then get in contact with the BBC and ask to see if they did broadcast it and if they are going to again.
