Instead they will see people with British accents, entertaining them , whilst teaching them the values of friendship, helping others and politeness. They will be educated without realising it. All of which is absent from Nickelodeon, Disney Junior or, even worse, Tiny Pop.
I'm not entirely certain why British accents are required, but your post does imply a certain...bias towards the homelands?
And I believe Tiny Pop now has the new My Little Pony, which is in my opinion one of the finest, best written cartoons produced for children in quite some time. It is absolutely superb, and I'm pretty certain that a series subtitled "Friendship is Magic" covers all the bases of "friendship, helping others and politeness". But I'm sure you'll dismiss it because it's made in Vancouver.
If you don't like the BBC, that's your loss, you obviously enjoy trash TV of the lowest standard.
Well that's not snobbish or patronising at all.
Go live in America or Australia for while, watch the local stuff, and then realise what you're criticising actually produces some of the finest TV programmes available, anywhere.
As a British ex-pat currently hiding out in Canada, you're surprisingly ignorant. Sure, the US has some quite astonishing crap, as does the UK, and the BBC is more than capable of producing both quality and crap - see "Two Pints" or the state of the modern Panorama for examples of the latter. That said, shows like The Wire, Deadwood, The West Wing, and so on all come from our American friends, and are quite excellent.
