In a sign of just how popular and recognised the show has become, its music and the style of the opening credits have been used in a trailer for the kids' show Ben and Holly's Little Kingdom. The trailer uses the GOT music and pans over the little kingdom they way the GOT credits pan through Westeros. Likely to be lost on B&H's target audience, I imagine (at least, I hope they're not watching GOT as well!) but will doubtless get some recognition from parents.
YouTube only has home-made recordings of the trailer so far but it's airing on Nick Jr and variants of that channel if anyone is curious.
