In 1997, Steve Jobs and company released a touching video that gave the world a sense of why Apple does what it does. "The Crazy Ones" can be viewed here:
In 2013, Tim Cook and company released what I consider to be an updated version of essentially the same thing, with a similar message. It's not a product video, nor is it a demo of any sort. Instead, it's a video that portrays why Apple does what they do. Very well done, in my opinion.
