One recent TripAdvisor review of the agrotourism destination Schrute Farms awarded four stars, lavishly praising the food, while another yielded just one star, casting aspersions on the owners’ sanity. This wild disparity is especially odd because Schrute Farms doesn’t even exist.

The farm “belongs” to Dwight Schrute of the NBC series “The Office” (and his eccentric cousin Mose). In September 2007, the show asked to use TripAdvisor, a travel Web site, in an episode in which Dwight turns his beet farm into a bed and breakfast. Christine Petersen, the chief marketing officer for TripAdvisor, was thrilled. “We don’t have a big marketing budget and don’t do TV ads,” she said. “This was the big time.”

TripAdvisor set up a review page, thinking it would be good for a quick laugh or two. Paul Lieberstein, who wrote the episode, called “Money,” never even went back to the site afterward. “We thought it would be fun, but then we didn’t think about it anymore,” he said in an interview.

But Schrute Farms is still doing big business — for TripAdvisor. Reruns and DVDs keep inspiring new visits to the site and there are now over 600 reviews (more than for many major Manhattan hotels, Ms. Petersen said).
