I haven't seen this on the TV, only online, but it still qualifies (I make up the rules after all!). This animation from Christian Aid as part of their Poverty Over campaign is great. It's a very compelling message: a list of man-made obstacles that mankind has overcome in our history, so why can't we do the same with poverty? And visually the animation is very clever - and simple.
