These days, big TV events are nothing without a second screen. In fact, you may have a second and third screen.
In addition to watching Super Bowl 50 on CBS, for example, and chatting about it on social media, you might be checking smartphone apps, like Facebook Sports Stadium, for scores, stats and your friends' comments.
An even more popular app is Bleacher Report's Team Stream. It's downloaded about 13 million times each month and, at 230 minutes per month, it's the most-used sports app among young men, according to FastCompany.
On Super Bowl Sunday, the Team Stream by Bleacher Report app will have live play-by-play mixed in with Twitter tweets, including from NFL reporters. It'll post scores and stats, and injury reports.
