CNBC: The NFL is teaming up with Snapchat to make it easier for football fans to share content on the popular social platform. Here’s how it will work: Snapchat users can turn on location services on their smartphones, so when they’re at certain NFL games and events they’ll be able to contribute to that particular NFL Live Story. Then people everywhere will be able to access the “Live Story,” which will be available on Snapchat for 24 hours after the event.
