SeaWorld is a United States chain of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Entertainment (one park will be owned and operated by Miral under a license). The parks feature killer whale, sea lion, and dolphin shows and zoological displays featuring various other marine animals. There are operations located within the United States in Orlando, Florida; San Diego, California; San Antonio, Texas; later outside the United States such as Abu Dhabi, United Arab Emirates; and previously Aurora, Ohio. On March 5, 2007, SeaWorld Orlando announced addition of the Aquatica water park to its adventure park, which already includes SeaWorld and Discovery Cove. SeaWorld parks also feature thrill rides, including roller coasters like Kraken and Manta at SeaWorld Orlando and Steel Eel and The Great White at SeaWorld San Antonio. Journey to Atlantis, a combination roller coaster and splashdown ride, can be found at all three parks. The parks were owned by Busch Entertainment Corp., the family entertainment division of Anheuser-Busch, which is best known for brewing beer. In 2009, Busch Entertainment was sold to the Blackstone Group and subsequently renamed SeaWorld Entertainment. In 2013, Blackstone sold 37% of SeaWorld Entertainment in an initial public offering, and sold its remaining 21% holding to Zhonghong Zhuoye in 2017. The parks' marine mammal collections have been the subject of public debate over the years. The 2013 documentary film Blackfish, produced after a SeaWorld Orlando trainer was killed by one of the park's orcas with a history of unpredictable and violent behavior, increased the scrutiny and has led to decreases in attendance, profits, and the company's share price. It is a major theme park competitor to Six Flags, Cedar Fair, Walt Disney Parks & Resorts, and Universal Parks & Resorts. In 2016, SeaWorld announced that they would end their in-park Orca breeding program, and eventually phase out their theatrical killer whale shows altogether (due to state legislation in California that banned shows using orcas) starting in San Diego. It was announced later in the same year, that SeaWorld would build their first park without killer whales and outside of the United States in Abu Dhabi, UAE.
