NBC‘s experiment with a newsmagazine in the iconic Thursday 10 PM time slot is over. The network just announced that midseason drama Do No Harm will move into the time period on January 31, following the hourlong series finale of 30 Rock, which will air the same night from 8-9 PM, The Office and newbie 1600 Penn. The low-rated Rock Center With Brian Williams will move to Fridays beginning February 8 and air in the “newsmagazine” 10 PM slot, bumping Dateline to 9 PM. Dateline will take over Grimm‘s slot while the supernatural drama is on a hiatus. When Grimm returns to its 9 PM berth March 8, I hear Dateline will either get off Fridays (by then the Sunday edition will already have launched post-football), or replace Rock Center if the show does not get any traction on its new night. “January 31 will be a special night as one classic series will mark its finale with a great hour-long sendoff episode while a promising new drama will make its debut on Thursdays,” said NBC chairman Bob Greenblatt.

Do No Harm faces long odds as NBC’s Thursday lineup is a far cry from the glory days of Must See TV. Both new drama series the network launched in the time period last season, Prime Suspect and Awake, fizzled. In Do No Harm, Dr. Jason Cole (Steven Pasquale) is a highly respected neurosurgeon who has a deep, dark secret. Every night at the same hour, something inside Jason changes, leaving him almost unrecognizable — seductive, devious, borderline sociopathic. Do No Harm is produced by Universal Television and Traugott Company. The executive producer-writer is David Schulner.
