New and Old Media, Participation, and Information
To read about "Disruptive Innovation", check out one of the best explanations (not in the video, but on the page) about it: http://www.claytonchristensen.com/disruptive_innovation.html
While the link from the main page calls this class New_and_Old_Media,_Participation,_and_Information the class introduction assignment calls this class (for March 2nd) Technology, Innovation, and Internet. I believe to both themes, this link is quite appropriate.
