Based on the long-running U.K. series "Ant and Dec's Saturday Night Takeaway", the ambitious live show featured stars stunts, hidden-camera pranks and audience giveaways. However, it failed to live up to the network's expectation.
The show, which sometimes benefited from a strong lead-in "The Voice", was averaging 5.8 million viewers during the season, which lasted eight episodes.
NBC won't cut ties with Neil Patrick Harris though, planning to work on new projects through the network's deal with the Emmy-winning actor's Prediction Productions.
"We are extremely proud of the work Neil and the producers did on 'Best Time Ever'," Paul Telegdy, NBC's president of late-night and alternative programming, tells Variety. "People rewarded us for taking the risk of trying something different. It was an incredibly complicated and sophisticated form of television to put on a live show on a weekly basis. We're proud of Neil for giving it his all and we have steely resolve to work together on something new."
