NBC has an early holiday present for those who may have not caught up with some of its new and returning series or want to re-watch them for free.
Starting Monday, the network is offering all previously aired episodes of its new fall shows "Up All Night," "Whitney," and "Grimm." It is also making the full season episodes of returning series "Parenthood," "The Biggest Loser," and "The Sing-Off" available.
