Here’s two short videos I taped a couple of years ago on the history of CSR and sustainable business.
Each is about five minutes and they were the most popular ones on the online course I used to run with Mallen Baker (at least, out of the videos I taped)
I have given this as a lecture to a number of audiences, and they seemed to like it.
If you want to watch them later, you can download from YouTube using this handy web-page.
