Three years, 20+ million online views, and many, many face-to-face showings later, the Did You Know? (Shift Happens) video still is going strong. Just this week it was mentioned in TIME magazine. Karl Fisch and I continue to get a bazillion e-mail messages about it…

Karl, XPLANE, The Economist, Laura Bestler, and I are very pleased to announce the release of Did You Know? 4.0, created for The Economist’s Media Convergence Forum in October.

I think XPLANE did an absolutely fabulous job with it, but let me know what you think in the comments. Downloadable versions and source files are available on the Shift Happens wiki under a Creative Commons license. Happy viewing (and please spread the word)!

Update: Be sure to read Karl's post on this too!
