 In January 2014, Iger announced that Frozen would be adapted into a Broadway stage musical. In the space of a single business quarter, Iger went from speaking of Frozen's "franchise potential" (in February 2014) to saying that it was "probably" one of Disney's "top five franchises" (in May 2014). The film's massive popularity resulted in an unusually severe merchandise shortage in the United States and several other industrialized countries in April 2014, which caused resale prices for higher-quality limited-edition Frozen dolls and costumes to skyrocket past $ 1,000 on eBay. By the time the merchandise shortage was finally resolved in early November 2014 (nearly a year after the film's release), Disney had sold over three million Frozen costumes in North America alone. Wait times for the meet-and-greets at Disney Parks soon regularly exceeded four hours and forced management in February 2014 to indefinitely extend what was originally intended as a temporary film promotion. Disney Parks later put on a temporary event (Frozen Summer Fun) at Disney's Hollywood Studios, then announced on September 12, 2014, that the Maelstrom ride at Epcot's Norway pavilion would be closed and replaced with a Frozen-based attraction, which opened in early 2016. By August 2014, the publisher Random House had sold over 8 million Frozen-related books. Tour operators, including Adventures by Disney, added more Norway tours in response to rising demand during 2014.
