OnlinePHD.org has published a fun interactive history of Google titled "When Larry Met Sergey" that tracks the company's year-by-year progress compared with the rest of the web.
Each year gives you a peek at the company's key metrics but more fun are the yearly lists of common search terms, big site launches, top memes, browser market share and the ever-beefy hardware Google uses to power itself.
Geeky but fun.
