Ban it. Stick with it. Choose REAL life !
My eldest (12) lived with the ex until last year in a house with no TV, computer or video games. He's amazingly well read, confident, socially able, happy in his own company, mature and creative. This from years of reading, making, talking, cycling, walking, music, plasticine, origami etc etc etc... He's not "bookish" or a spod - he's just a great kid who knows what real life is.
The other two (7 and 5) who have grown up with me and the TV are difficult, impatient, have no empathy but know five words in Spanglish (thanks Dora) are using lots of nasty Americanisms and Australian Questioning Inflection.
The eldest, having been at bog standard state primary recently sailed into a VERY competitive selective Grammar school, the other two (at expensive prep school) aren't struggling exactly but are certainly not on track for academic brilliance.
I'm getting rid of the TV as a new years resolution (literally getting rid - down to the charity shop) and bringing on books, painting, making stuff, origami, plasticine, cooking and generally re-inventing a 1960's childhood that includes the REAL WORLD a lot more than a flat screen version of something that will never exist.
The whole "third parent" thing is a vile nonsense. If I haven't got time to sit and talk, make a paper boat, colour in a spelling book or shake a maraca then what exactly is it that I'm doing instead that's SO important ?
Plus save £145 a year on the license, a fortune on the Virgin media crap and your kids will have to IMAGINE what they'd like for Christmas, what they'd like to look like (instead of what they SHOULD look like) and they will never, ever get the real joy of Peter Pan or Pinnochio from Spielberg (Or the sainted CBeeBies).
