About the article "SeaWorld", section "History".

Candidate passages:
SeaWorld was opened in 1964 by Milton C. Shedd, Ken Norris, David Demott, and George Millay.
The four graduates of UCLA originally set out to build an underwater restaurant and marine life show.
When the underwater restaurant concept was deemed unfeasible, they scrapped those plans and decided to build a park instead, and SeaWorld San Diego was opened on March 21, 1964.
With only a few dolphins, sea lions, 6 attractions and , the park proved to be a success and more than 400,000 guests visited in the first 12 months.
After considering other locations in the midwest, including the Lake Milton/Newton Falls area west of Youngstown, Ohio, it was decided that Aurora, Ohio would be the new home of a SeaWorld.
The Aurora site was approximately northwest of the Lake Milton site, and southeast of Cleveland.
By this time the founders of the company had captured a few more species of animals, including a killer whale that was brought to the new facility.
The harsh winter climate permitted the park to be open only from mid-May until mid-September.
The Walt Disney World Resort in Orlando, Florida opened near the end of the second operating season of SeaWorld of Ohio.
The success of Disney in Orlando provided a location that was already popular with tourists.
SeaWorld Orlando opened in 1973.
Harcourt Brace Jovanovich, Inc. (HBJ) purchased the company in 1976 and 12 years later they began a venture in Texas.
In 1988, SeaWorld San Antonio opened just a few miles outside of San Antonio.
Growth has pushed the city outwards, and now SeaWorld San Antonio lies in the Westover Hills community in West San Antonio.
The park was open year-round like its sister parks in California and Florida in 1988 and 1989, then went to a seasonal schedule.
The stress and financial resources it took to build and maintain a state-of-the-art marine mammal facility in the late '80s eventually took its toll on the company.
HBJ, whose primary focus was producing school books, needed to reduce its assets in order to avoid a bankruptcy.
The Anheuser-Busch Company made an offer to purchase the SeaWorld parks.
However, HBJ also owned and operated two other parks, Cypress Gardens and Boardwalk and Baseball, and out of fear of not being able to find a buyer for the two other parks, HBJ refused to sell the parks individually.
Despite a long negotiation, Anheuser-Busch bought all six parks in 1989: SeaWorld in San Diego, Aurora, Orlando and San Antonio as well as Cypress Gardens in Winter Haven and Boardwalk and Baseball in Haines City.
Soon after the sale was final, Busch sold Cypress Gardens to the park's management and closed Boardwalk and Baseball.
Anheuser-Busch put millions of dollars back into the parks to revive and to prolong their longevity.
Busch Gardens is the name of two amusement parks in the United States, owned and operated by SeaWorld 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.
In 2009 InBev, the new owners of Anheuser-Busch, sold the amusement parks to the Blackstone Group.
Blackstone has kept some of the popular traditions including a stable with Clydesdales but those Clydesdales are not affiliated with the beer company. 
As with all breweries in the country, the Temperance movement and eventual Prohibition in the United States dealt a major blow to the company in the 1910s through the 1930s.
Some of the products sold by Anheuser-Busch to survive during Prohibition included brewer's yeast, malt extract, ice cream, and Bevo, a nonalcoholic malt beverage.
The St. Louis Cardinals major league baseball club was owned by Anheuser-Busch from February 20, 1953, until the club was sold to a group of private investors on March 21, 1996.
Busch Memorial Stadium, paid for and built by the brewery and opened in 1966, was demolished in late 2005 and replaced by a new ballpark in 2006.
Anheuser-Busch signed an agreement to retain the "Busch Stadium" name on the new building through 2025.
Anheuser-Busch became the largest brewer in the United States in 1957.
Up until 2009, Anheuser-Busch was also one of the largest theme park owners/operators in the United States, with ten parks throughout the country through its entertainment division, Busch Entertainment Corporation, including its 3 SeaWorld locations.
On October 7, 2009, parent company Anheuser-Busch InBev announced plans to sell the division to The Blackstone Group for up to $2.7 Billion USD.
Anheuser-Busch International, Inc., was established in 1981 as a subsidiary responsible for the company's international operations and equity investments.
Prior to its 2008 acquisition, Anheuser-Busch operated 15 breweries internationally: 14 in China and one in the United Kingdom.
Chinese production of Anheuser-Busch products began after the company's purchase of a local brewery in 1997; later, the company operated both Budweiser Wuhan International Brewing Company and Harbin Brewery, which Anheuser-Busch fully acquired in 2004.
In the United Kingdom, the Budweiser Stag Brewing Company produced and packaged Budweiser at the Stag Brewery in Mortlake.
At one time, Anheuser-Busch International also held investments in Grupo Modelo in Mexico and Tsingtao Brewery in China; Anheuser-Busch itself also held investments in Redhook Ale Brewery of Seattle, Washington and Widmer Brothers Brewery of Portland, Oregon.
After the 2008 acquisition, most international operations were transferred to AB InBev zones where the interests are located.
The company introduced a flavored 12% abv malt liquor under the name "Spykes" in 2007.
It was sold in colorful, 2-ounce bottles.
Available flavors included mango, lime, melon and chocolate.
It was withdrawn in the same year after criticism from alcohol industry watchdog groups that it was being marketed to underage customers, and the Alcohol and Tobacco Tax and Trade Bureau found that the labeling of Spykes was illegal.
On June 12, 2008, Belgian-Brazilian brewing company InBev announced that it had made a US$ 46 billion dollar offer for the company.
which if it was accepted would join two of the world's four largest brewing companies (based on revenue) and create a company brewing three of the highest grossing beers in the world, namely Bud Light, Budweiser, and Skol.
InBev also stated that the merger would not result in any U.S. brewery closures and they would also attempt to retain management and board members from both companies.
On June 25, 2008, Anheuser-Busch officially announced that they would reject InBev's offer and provide a restructuring of company to maintain shareholders and United States World Headquarters in St. Louis.
On July 1, 2008, InBev urged Anheuser-Busch shareholders to vote in favor of the buyout as InBev felt the offer of $65 per share should be considered a reasonable offer in view of the falling stock market.
The company had previously filed suit in Delaware, after the rejection of their offer, to ensure that the stockholders could oust Anheuser-Busch's 13 board members.
On July 7, 2008, Anheuser-Busch filed a lawsuit against InBev to stop them from soliciting support of shareholders, stating that the company's offer is an illegal scheme.
InBev was also accused of concealing that they do business in Cuba, which might have created additional obstacles to their efforts to operate in the United States.
On July 13, 2008, Anheuser-Busch and InBev said they had agreed to a deal, pending shareholder and regulatory approval, for InBev to purchase the American icon at $70 per share, creating a new company to be named Anheuser-Busch InBev.
Anheuser-Busch would get two seats on the combined board of directors.
The all-cash agreement, almost $52 billion in total equity, created the world’s largest brewer, uniting the maker of Budweiser and Michelob with the producer of Beck's, Stella Artois, Hoegaarden, Leffe, Bass, Labatt and Brahma.
The two companies had combined yearly sales of more than $36.4 billion, surpassing the current No.
1 brewer, London-based SABMiller.
Grupo Modelo took inBev to arbitration for more than a year and a half after the deal was completed over whether they could block the deal.
In July 2010 a Panel decided that the takeover did not violate Anheuser-Busch agreement with Modelo 
Anheuser-Busch initially created the subsidiary to run the various Busch Gardens parks.
The parks at Tampa, Florida and Williamsburg, Virginia were located adjacent to breweries, and the parks included tours of the facilities and even free samples of the products made there.
In 1989, Anheuser-Busch purchased the theme park unit of publisher Harcourt Brace Jovanovich, which included the SeaWorld family of parks.
The purchase also included two other parks in Central Florida: Cypress Gardens and Boardwalk and Baseball.
Boardwalk and Baseball was promptly closed, while Cypress Gardens was later sold and transformed into Legoland Florida, which opened in October 2011.
The parks were managed out of Anheuser-Busch's headquarters in St. Louis, Missouri until 2008, when the company relocated the division to Florida, where five of the company's ten parks were located.
In 2008, Anheuser-Busch was acquired by Brazilian-Belgian brewer InBev.
Based on its previous acquisitions, it was widely expected that InBev would later sell off non-core assets in order to pay down the debt created by its purchase of Anheuser-Busch; the theme-park division was considered one of the most likely assets to be sold.
In early 2009, InBev began soliciting bids for those assets in advance of an anticipated sale.
As part of the plans to shed the division, Busch Entertainment ended the free beer-sampling programs at those parks that had them.
Similarly, Busch Entertainment broke from its parent company and terminated a benefit where employees of legal age received two free cases of Anheuser-Busch beer per month, a benefit that continued for the rest of the company.
At the time, InBev was thought to be considering selling the parks to the highest bidder, or spinning off Busch Entertainment as an independent company.
It was suggested at one point that NBC Universal was interested in purchasing Busch Entertainment, and folding it into the Universal Studios Theme Parks chain, but no official bid for the company surfaced.
However, other asset sales, such as the sale of Tsingtao Brewery, and an issuance of $3 billion in new long-term debt in May 2009, raised over $11 billion since the start of 2009, temporarily reducing the need to sell Busch Entertainment.
Other cited reasons for an apparent reluctance to sell off the company included still-volatile credit markets and receipt of initial bids that were lower than expected. 
Anheuser-Busch Companies, Inc. is an American brewing company and a wholly owned subsidiary of Anheuser-Busch InBev (AB InBev).
The company operates 13 breweries in the United States.
Until December 2009, it also was one of the largest theme park operators in the United States, operating ten theme parks through the company's family entertainment division, Busch Entertainment Corporation.
It is based in St. Louis, Missouri, which is also the headquarters for the AB InBev North America unit.
