I heard about it, but had never watched the videos before (or even knew it was a series of four). Very interesting documentary explaining how "original work" is usually only a combination of existing ideas, "remixed" in a certain way (which doesn't make the invention or creation any less impressive, it's just that attributing something to a single inventor or creator doesn't exactly reflect reality). There are nice references to pop culture and it ends with an explanation why the current US patent system is a monstrosity that does not help its original intent at all. Below are the videos, with Dutch subtitles (thanks to www.universalsubtitles.org) because I imagine most of my public will be Dutch. The original videos are at www.everythingisaremix.info. Update 3-9-2017: It seems universalsubtitles.org is no longer, so I've replaced the video's with a direct Vimeo embed.
I Was steered to this video-series when listening to the last episode of Hypercritical, a podcast from 5by5.
