"Amazon was a large river in South America. Ryanair was an Irish airline that flew to places nobody had ever heard of. eBay was a typo. Yahoo was a term from Gulliver's Travels. A googol was a very large number (one followed by a hundred zeroes). Classified ads were densely printed matter in newspapers. 'Encyclopedia' was a synonym for Encyclopedia Britannica."

Lots of other good reads if you have the time.
