Building the NBC News Big Board

EJ Fox recounts building the NBC News Big Board, the touchscreen map Steve Kornacki uses live on election night before roughly 10 million viewers.

Fox describes editing JSON, VPNing in, and restarting servers from his couch, then watching changes hit air minutes later, and the stress of handing a live performance to someone else.
