Analysts who follow Comcast are upbeat about its parks. Jessica Reif Cohen of Merrill Lynch called the segment's third-quarter results "very impressive" during the conference call.
"It seems pretty clear that new attractions drive attendance," she said.
Doug Mitchelson, an analyst with Deutsche Bank, predicted this week that the NBCUniversal theme parks will reach nearly $2.5 billion in annual revenue by 2015 — double the $1.2 billion in yearly sales they produced in 2009.
Burke said he thinks the theme parks also help NBCUniversal's other businesses, including film, television and, eventually, consumer products, in much the same way parks and resorts feed Walt Disney Co.'s other operations.
