The scheduling device, which extended the network's comedies by five or 10 minutes with extra footage and commercials, won't be incorporated into the programming menu in the fall, Zap2It.com reported Tuesday.
Vince Manze, NBC scheduling chief, said the extra time wasn't as effective as it was when introduced.
"It was a good idea when we started it. It was very novel. But it's just not a good idea to have shows starting at 9:23 p.m.," Manze said. "I don't think anyone here thinks, at this point, super-sizing often is good for the shows."
Super-sizing was the brainchild of then-NBC Entertainment President Jeff Zucker, who expanded episodes of "Friends" during the 2000-01 season, in part to prevent people from switching to "Survivor" on CBS.
NBC still plans to produce five hourlong installments of "The Office" for the fall, officials said.
