Netflix has a lot at stake on Christmas Day, and one basic job: Don’t screw up. The company will be livestreaming two National Football League games with postseason implications, aiming to cement itself as a major player in live sports to woo subscribers and advertisers.

Despite hiccups with a boxing match, the ad revenue a live football double bill would bring is one of the reasons it's worth the gamble.

The streaming giant will have one of its biggest days since the site launched in 1998 when it airs two NFL games for the first time.
