In what may well turn out to be the highest-rated Christmas TV special ever, ABC's animated Shrek the Halls drew a whopping 21.06 million viewers Wednesday night and led into a repeat of How the Grinch Stole Christmas that retained 18.74 million. The Shrek special registered an 11.0 rating and a 17 share, while Grinch landed a 9.4/17. However, the network's ratings collapsed after those two half-hour specials, which aired in the 8:00 p.m. hour, and CBS wound up winning the night with strong ratings for Criminal Minds at 9:00 p.m. and CSI: NY at 10:00 p.m. The night marked the official end of the November sweeps. CBS is expected to retain its crown as the network with the largest overall audience during the month, while ABC is expected to win among adults 18-49.
