This season, repeats of decades-old animated holiday treats have drawn larger audiences than first-run TV fare – the most heartening example of which being the fact that ABC’s repeat of A Charlie Brown Christmas outdrew the season finale of Fox’s The X Factor. Good grief, Simon Cowell! And tonight, this Grinch cartoon, from 1966, figures to provide some holiday cheer as well, for the network as well as its viewers. ABC follows this telecast with an 8:30 p.m. ET presentation of the 2000 live-action movie Dr. Seuss’ How the Grinch Stole Christmas, starring Jim Carrey, but stick with the original.
