This is it for me, young kids are completely blown away by seeing the pitch and stadium for the first time. They are memories that stay with you and ones that I would not want my kid(s) to miss out on. Who knows, once they get a bit older things might have changed.
There's always been glory kids around, they usually end up saying they support Newcastle 10 years later. I know loads who 'supported' Liverpool, Everton, Man U etc, who now don't.
Streaming live games seems to be where its heading so it wouldn't surprise me if the TV companies start offering these kind of deals. I imagine it would just further swell the coffers of the clubs as they take a cut from each subscription. Could generate huge cash.
