revealing an entirely new market they had never considere
Well, Harrods in London started as a corner-shop greengrocers. It's just business at the end of the day - set up a good location and build a brand and generally you find you can sell pretty much anything to pretty much anyone.
The online world is really not all that different to a traditional bricks and mortar business. Both require marketing, and there's always more than one angle, and frequently that one angle will expose the others.
