eBay is big. Very big. At any given time, there are over 18 million items for sale, with an average of $680 worth of transactions taking place every second. And these numbers will undoubtedly be even higher by the time you get around to reading this.

But like most big things, eBay started out small. As the story goes, eBay was born of a dinner conversation between Pierre Omidyar and his wife, Pam, about PEZ® dispensers. As it turns out, this, like many origin stories, is a myth (this one was cooked up by eBay PR whiz Mary Lou Song); but the fact remains that eBay still has that PEZ-dispenser feel, and that's what keeps customers coming.
