My personal favourite is the Angel Falls one.
It isn’t that long ago when we were all happy with videos that were no bigger than 320*320 and not very clear either. These files demonstrate what full quality video can look like in reasonably sized files – 1 minutes in 50MB. Having said that, there was a time when I would have thought that anything taking 50MB was completely unreasonable.
If the programme makers continue to make stuff like this they have nothing to fear from the likes of YouTube.
