Some NBC schedule shifts, according to a good source (but as yet unconfirmed by the network):
–NBC is going all-comedy on Thursdays, adding extra episodes of "The Office" and "Parks and Recreation" to the 10 p.m. hour. It’s another sign the network may expand comedies — or maybe "Love Bits," a new comedy anthology — into the late hour next fall.
–Just-renewed "Parenthood" will get a repeat run Saturdays at 8, starting this week.
–"Minute to Win It" will get a run Wednesdays at 8 during the summer, starting July 7. It will be mostly original episodes. NBC may also air "Minute" on Mondays at 9 in August.
