Do you know Big Data success stories for a general audience?

I'm trying to collect the most impressive stories of applications of Big Data for a presentation for non-geeks. I'm looking for something that people can relate to and that it's not impressive from the technical side. For example: Target predicting pregnant women: - http://www.forbes.com/sites/kashmirhill/2012/02/16/how-target-figured-out-a-teen-girl-was-pregnant-before-her-father-did/

Facebook predicting your partner: - http://www.huffingtonpost.com/2014/02/14/facebook-relationship-study_n_4784291.html

UPS predicting avoiding turning left will save time and money - http://www.businessinsider.com/save-money-gas-avoid-left-turns-2012-3

Do you have any other success stories? Maybe related to healthcare, finance, science?
