Really interesting mini documentary here from US public service broadcaster PBS looking at the phenomenon of “Viral Video.

While ten years ago it took ten months for a video to go viral today with social networks that can happen in a day.

Whether it its babies, dancing or otherwise, cats, schadenfreude humour or terrible songs this looks at how the YouTube the viral video has developed and where it is going next.

There are many interesting points made here, but the idea that as well as entertaining us these YouTube videos (other videos services do exist) are also how we will remember certain moments in history.

Whether it is the Arab Spring in Egypt an the man in front of the water cannon or the woman who is savagely beaten by police.

PBS has also compiled a great list of all the videos featured in this documentary here.
