These days, the National Football League, BMW, and Uber have something in common — they’re all experimenting with big data in exciting new ways. The NFL is using big data to help football fans track how fast and how far their favorite players sprint during a game. BMW is using big data to help drivers anticipate upcoming traffic light changes, and determine whether they need to speed up or slow down to make the light. And Uber is using big data to predict where riders want to go even before they get into the car.
