The TVLine-Up: What's Returning, New And Leaving The Week Of Dec. 18

This weekly feature is in addition to TVLine's daily What to Watch listings, monthly guide to What's on Streaming and seasonal Holiday Movie Roundup.

With more than 500 scripted shows now airing across broadcast, cable and streaming, it's easy to forget that a favorite comedy is returning, or that the new "prestige drama" you anticipated is about to debut. So consider this our reminder to set your DVR, order a Season Pass, pop a fresh Memorex into the VCR... however it is you roll.
