As an example, I'll just draw on my past life as a retail marketer.
I would be a member of a coalition program, one like air miles. We would collect and get access to the data of what our customers would be using air miles for and how it would impact the sales, but we also could get access to data from air miles more generally, like what people of certain profiles are doing, but it wouldn't necessarily be with an individual identifier on it. It would be people in a certain income bracket or geography or whatever who have these other purchasing patterns so I could draw some conclusions.
That's a case where I might be buying or getting anonymized data as a marketer. Is it that kind of thing?
