Online sales (2012 estimate): $10,600,000,000

Staples, Inc. (NASDAQ:SPLS) might be the runner-up in our countdown, but it is the first online retailer to surpass the $10 billion mark in online sales. The largest office supply retailer in the world went online in 1998, after it had already achieved success with its offline stores. More than a decade since then, Staples has definitely made a name for itself in the world of online stores.
