Netflix is going all out for its debut with an NFL Christmas doubleheader. The games were on Christmas and that tied into having a special singer perform a taped performance before kickoff of the Chiefs-Steelers game.

The list of stars involved in Netflix's Christmas broadcast of two NFL games doesn't end with the players on the field and the 22-person cast of on-air talent. Singer/songwriter Mariah Carey will kick off the holiday festivities on Wednesday with a pre-recorded performance of her hit single "All I Want for Christmas Is You.

CBS Sports produces the games itself for Netflix, while NFL Media produces the pre-, post, and studio halftime programming. EverWonder Studio will executive produce NFL Christmas Gameday.
