When I turned on the TV this morning (after a sleep in), I noticed that channel 9go had an 8 hour marathon of My Little Pony, with about 12 episodes and a movie at the end.
It seemed a bit weird, having a massive block on like that, unless today was some sort of anniversary... but even still, channel 9 isn't the sort of network that cares about things like that for kids cartoons. The ABC or SBS is where you'd normally find a big random block of the one tv show like that.
(even though I have just about every Hasbro cartoon on DVD or recorded, I'd still love to see a big marathon block of TFs episodes on TV)
