As of August 2015, Seaworld profits have dropped 84% compared to the period prior to this film's release.
During his time at Seaworld, Tilikum was housed in a tank containing 0.0001% (one one-millionth) of the quantity of water that he would traverse in a single day in the ocean.
In late 2015, Seaworld announced they would be ending their orca shows in 2016, and replacing them with attractions that promote conservation the following year. This has been widely panned and is viewed as a PR stunt by animal rights groups, as Seaworld will continue to breed the animals and keep them in captivity. Because they refuse to end their breeding program, Seaworld's proposed "Project Blue World" was denied the necessary permission to expand their park in San Diego.
There are currently 58 known captive orcas worldwide. 163 have died in captivity, there have been 30 stillborn calves, 14 known capture attempts that resulted in deaths, and 43 that were captured but are unaccounted for.
Jurassic World (2015) director Colin Trevorrow told Empire Magazine that Blackfish (2013) was a big influence on the movie. The behavior of the captive Indominus Rex, was based on Tilikum's behavior in captivity.
