** Vipul: Stock price chart?✔

** Vipul: For some rows, adding a bit more "forward-looking" information on the eventual importance of the development would be nice. Example rows where this would help: introduction of Free Super Saver Shipping✔, introduction of Amazon Prime✔, launch of the Kindle✔, launch of Mechanical Turk✔, launch of Amazon EC2 / Amazon Web Services✔, and Jeff Bezos buying the Washington Post✔ (this could be tied to later criticisms by Trump of the Washington Post being a newspaper peddling Amazon's interests). Basically with that done, it will be easier later to trim the timeline and move further developments into smaller timelines; also even until then, having initial events include more of a forward-looking perspective makes the timeline more valuable.
