In February 2001, Anheuser-Busch sold the SeaWorld Ohio park to Six Flags, Inc., operators of neighboring Six Flags Ohio. Upon completion of the sale, the two parks were combined in spring 2001 as the so-called "mega-park" "Six Flags Worlds of Adventure", which boasted its "three parks in one" uniqueness: a waterpark, an amusement park, and a wildlife animal park, all included in one price of admission. SeaWorld executives replied that their park was sold because of the short season of the animal park, Northeastern Ohio's cold winter months, and also because they were not able to get the necessary permits to build roller coasters like the other SeaWorld properties had been able to.
