By that I mean channels 1-5 and when they are airing the show; as opposed to watching it on catch-up/later on if recorded?
The only time I watch when it’s actually airing is BB, Eurovision or Apprentice. Can’t recall any other time in recent years when I have (except Wallace and Gromit at Christmas

).
Apart from a few things like Planet Earth, I can’t even recall any show I’ve watched from those channels at a later time.
