From the article: "In a move that could lay bare the inner workings of the
consumer data industry, eight members of Congress have opened a sweeping
investigation into data brokers — companies that collect, collate, analyze and
sell billions of details annually about consumers’ offline, online and mobile
activities for marketing and other purposes…. The Congressional inquiry
heightens the scrutiny of a largely unregulated industry whose companies sell
their services to third parties, rarely interacting directly with consumers."
