It’s interesting to see how the definition of “tech company” has expanded. Only one or two of these companies create and sell software or technology. These are startups, maybe, and I think we can talk about where the “innovative” companies are. But these are companies that run platforms online, or use the web to sell products in novel ways. They seem very different from most of the companies on the parent comment’s list.

This is partly a side effect of tech becoming so big, it's segmenting into products vs services. For example, Tinder isn't directly selling software to anyone, it's selling a dating service that runs exclusively on software. You could say the same about Facebook, what software is it selling directly to consumers?

None. It's selling a social network service to its users and an ad network service to its clients, built entirely on software.

Sure. Tinder and Facebook are tech firms, and so is Bloomberg.

That mattress company you put on the list isn't. Lines in the sand, yadda yadda, slapping a website on a store doesn't make it "tech".
