You have to check out these info viz diagrams from Jer Thorp entitled NYTimes: 365/360 which show the top organizations and personalities for every year from 1985 to 2001. Jer even provides source code (more here) and explanations. This is exactly why I wanted to attend Hack Day, but alas I am on the waiting list.
