SeaWorld has struggled to regain its footing after a documentary in 2013 criticized the treatment of its orca whales used in live shows at its amusement parks. The company originally cited weather, higher ticket prices and calendar changes for decreasing visitors to its parks, but last August, management acknowledged that the film was hurting ticket sales.
In response, CEO Joel Manby, who took over two years ago, ended SeaWorld's orca breeding program. The company has also introduced a new show at its San Diego, California, park that has animal performances focused on actions more likely to be found in nature. Other new shows are seeking to decrease reliance on the creatures, Manby said at the annual shareholder meeting last month.
The company operates 11 parks in the United States, including SeaWorld, Bush Gardens and Sesame Place, according to its website. SeaWorld has also partnered with Chinese developer and tour operator Zhonghong Holdings Group to open parks in Asia, and it is opening two new locations based off Sesame Street, the children's show on Public Broadcasting Systems Inc.
Tickets to its Orlando, Florida, location start at $79.99, according to its website.
Here are six other companies providing entertainment for families that may be stealing Seaworld's sales.
