Competitive intelligence.

Crawling thousands of website, mashing up the data to analyze competitiveness between them, and selling it back.

For example, cost of flights. Different websites provide different prices for the same flight. The technology crawls all the prices, combines the data, then resells it back to the websites. Everyone knows everyones prices, keeps competition high, lower prices for consumers.
