This year closes with the worldwide, national, and local premieres of 34(!) British, Irish, and Canadian TV programs.
British TV Premieres in Dec 2019: Call the Midwife, Deep Water, Midsomer Murders, The Sweeney & More

I haven’t counted, but I’m guessing that right behind the number of holiday movies and television programs featuring Santa (a.k.a. Father Christmas) is the one for filmed adaptations of the classic A Christmas Carol by Charles Dickens.
