I'm not sure I'd call facebook (media), Amazon (retail, logistics), uber (cabs) etc. technology companies now either. Yes, they are heavily technology-leveraged, but ultimately the machine under the covers matters less than what it achieves. Walmart, like many large companies, is identifying that significant new business opportunities can be released by better leveraging technology. Does that make it a "tech company"?
