NBC is moving low rated reality competition series American Dream Builders to Sunday at 7PM from Sunday at 8PM beginning this Sunday, April 20. The current timeslot occupant, Dateline, moves to 8PM. The most recent episodes of American Dream Builders earned a 0.7 adults 18-49 rating while last Sunday’s Dateline earned a 0.8. However, other Sunday episodes of Dateline this spring have fared better, with the March 9 episodes garnering a 1.1 adults 18-49 rating. NBC may hope that Dateline will provide a stronger lead-in to its struggling dramas Believe and Crisis.
