Until I googled it just now, to find out what you're on about, I'd not even heard of the National Television Awards! (I knew about the BAFTA TV awards but the NTAs seem to have passed me by altogether).
I've heard of most of the nominees but, apart from those series that I might occasionally have watched many years ago (such as Eastenders, Coronation Street and The Vicar of Dibley), I've never seen any other programmes listed:

(I don't think that I've ever watched anything featuring Ant and/or Dec and 'reality TV' leaves me totally cold).
I hardly ever watch telly (although I make a few exceptions, such as for new episodes of Air Crash Investigation or for The Voice Kids). I get most of my entertainment from internet radio, or occasionally from French cinema DVDs, and nearly all of my news from the internet too.
