bse-timeline-as-revealed.swf (application/x-shockwave-flash Object)
There is a benefit to this approach, which shows in broad strokes when major new information was revealed to the public, and in an alternative view when it was happening. Alas, there isn’t enough detail to use this as more than a cheat sheet, but for a quick summary it’s certainly useful. (If the text is too small make your browser window bigger, the text will get bigger, too.)
