It's really about 'core' to the business which relates to vertical integration. How much of your product do you make versus buy? If you are an information business and you make the tools that deliver your product then I think of you as being also a technology business. If you are an information business and you buy the tools that deliver your product then you aren't also a technology business.

Typically companies that have that technology component are able to respond faster, more creatively, and in a much harder to compete with way than companies that buy their base technology from third parties. The get a valuation boost from that.
