When I think of data mining, I think of a company finding ways to derive useful information out of its OWN data, typically historical in nature. Consider the work of Actuaries, for example. Companies collect all kinds of data, and "mining" that data is about finding correlations, learning what predicts what, exposing causalities; stuff like that.
Data COLLECTION is what Microsoft, Google, NSA, and others do. That data is then mined by Advertisers, Law Enforcement, or the parasites, to get information useful to them out of it.
