NBC got religion Wednesday and got ratings in the process. A one-hour Dateline special about the religious musings found in the best-selling novel The Da Vinci Code won the 8:00 p.m. hour with a 7.4 rating and a 12 share, beating a repeat of ABC's hit Lost, which drew a 6.9/11. At 9:00, NBC's Revelations debuted with a heaven-sent 9.9/15, far ahead of the network's average for that timeslot. (The biblical whodunit was nevertheless topped by Fox's American Idol, which recorded a 14.5/22.) NBC took the lead at 10:00 with Law & Order, which drew an 11.5/19 and beat CSI:NY, which registered a 7.1/12.
