I've been searching for a presentation I saw online a couple of years ago, without any joy. The presentation was about 20 minutes long. It started out describing the history of IT, then compares this to the history of the Green Movement, and how that is changing to the Blue Movement.

Anyways, I found this article which I really enjoyed:

If anyone knows the whereabouts of the presentation I'm looking for, please post a comment.
