Busch Gardens is the name of two amusement parks in the United States, owned and operated by SeaWorld Parks & Entertainment, a division of Blackstone Group. One of the parks is in Williamsburg, Virginia, and the other is in Tampa, Florida. There were also previously Busch Gardens parks in Pasadena, California (1905–1937), Van Nuys, Los Angeles, California (1964–1979) and Houston, Texas (1971–1973). Busch Gardens parks were initially developed as marketing vehicles for Anheuser-Busch and featured hospitality houses with samples of Anheuser-Busch products. They also included stables that housed many of the company’s Clydesdale horses, which have been associated with Anheuser-Busch since 1933. Eventually, rides and attractions were added to the parks and over time were developed into full theme parks while still promoting Anheuser-Busch. Busch Entertainment Corporation, now called SeaWorld Parks & Entertainment, was created as a subsidiary of Anheuser-Busch Companies to run the various parks in 1959.
