There is a beautifully told story about Youtube, how it started and how it changes the world. Anthropology professor Michael Wesch spoke at the US Library of Congress in 2008 about the "anthropological introduction to YouTube'. What you will see is an amazing insight into a world that you probably didn't think you would find interesting. You'll learn about the 'Numa Numa song', a music video from a Moldovan-Romanian band that makes it all the way to Japan, gets newly interpreted and goes to the US, where a guy dances hilariously to it and records himself on video, which in turn gets sent all around the world and was probably watched 600 million times. And that was in 2004, 1 year before YouTube even started. You will also find out about all the amazing ways that humans are sharing with each other, celebrating the joy of life, adding their own interpretation to a video and all joining in.
The video unfortunately is blocked in certain countries due to copyright issues with music in it, but if you search a bit you might find it.https://www.youtube.com/watch?v=0F_EOquQtZg
