If you have a square screen thing in your hand/kitchen/living room/bedroom or a tablet/laptop etc and you watch programmes made for television on it, are you watching television?
Or does it only refer to the watching of programmes broadcasted live at that moment on a piece of static equipment typically found in your living room?
Would it be odd to say that you don't watch television, but you do watch series and box sets on Netflix/Amazon Prime etc and BBC iplayer, ITVX? If I record program on a Sky+ and watch it tomorrow on my phone, is it still watching television? What about YouTube etc?
We had a bit of a 'debate' about this the other day, so
YABU - it's only called watching tv when it's live on a television
YANBU - you're watching the tv if it's a programme on a screen
(I'm leaving the watching of films on any media out of this as going to the cinema just makes things messy. This is about programmes traditionally made for television)
