In 2007, the park hosted approximately 9.51 million guests, ranking it the fourth-most visited amusement park in the United States, and seventh-most visited in the world.
Dedication
The World you have entered was created by The Walt Disney Company and is dedicated to Hollywood—not a place on a map, but a state of mind that exists wherever people dream and wonder and imagine, a place where illusion and reality are fused by technological magic. We welcome you to a Hollywood that never was—and always will be.
—Michael Eisner, May 1, 1989
Park development

The idea that led to the Disney Hollywood Studios began at its sister park, Epcot. A team of Imagineers led by Marty Sklar and Randy Bright had been given an assignment to create two new pavilions for the park's Future World section. The fruits of the brainstorming sessions were the Wonders of Life pavilion and the Great Movie Ride pavilion. The second of the two was to have sat between the Land pavilion and the Journey Into Imagination pavilion, and was to look like a soundstage backdrop, with a movie theater-style entrance in the middle. The actual attraction is very similar to the plans for the equivalent at Epcot, only, when newly-appointed CEO Michael Eisner saw the plans for the pavilion, he requested that, instead of placing the ride in an already existing park, it should be surrounded by a brand new theme park which extended the showbiz, Hollywood and entertainment theme.
Attractions
The park consists of six themed areas. Unlike the other Walt Disney World parks, Disney's Hollywood Studios does not have a defined layout; it is more a mass of streets and buildings that blend into each other, much like a real motion picture studio would. The layout of the park, however, did have an interesting design characteristic. If you look at an older version of a park map and turn it upside down (or look at an old aerial photo oriented due north), you will see a Hidden Mickey in the overall layout of the park. Recent construction and changes to the park have eliminated much of this image.

Animation Courtyard
This section of the park originally was the starting point for the tours of the park's active production studios. Its entrance is marked by a square "studio arch," much like a real Hollywood studio lot entrance might be marked. In the spring of 2008, Animation Courtyard was expanded to include portions of the former Mickey Avenue section of the park.
Pixar Place
The park's newest section includes many of the original soundstages used when the park hosted actual production facilities. Today, Pixar Place resembles the Emeryville, California campus of Pixar Animation Studios.

Live entertainment
Disney's Hollywood Studios has featured numerous forms of in-park entertainment throughout its history. During its early years, the park featured the "Star Today" program, with a daily celebrity guest. The celebrity would often be featured in a motorcade along Hollywood Boulevard, or would take part in a handprint ceremony at the Great Movie Ride's entrance, or even participate in an interview session.
At other times, Disney has imported characters that were not part of its own library of films and television shows. Some of these characters have included the Teenage Mutant Ninja Turtles, Ace Ventura, Pet Detective and characters from the Goosebumps series by author R. L. Stine. The Mighty Morphin Power Rangers made appearances in the park during the first seasons of the television series, but then vanished. Disney now owns the Power Rangers franchise through its purchase of Saban Entertainment, and are again regular members of the park's cast of characters, with characters from the more recent versions of the show, including the current edition, Power Rangers: Jungle Fury.
Many of the park's costumed entertainers are not related to any particular film or TV show. Instead, they are live-action caricatures of figures from Hollywood's history. Originally dubbed "streetmosphere" by Disney and now called the "Citizens of Hollywood", they appear at regular intervals on Hollywood and Sunset Boulevards. Some of these characters include directors, talent agents, starlets or hopefuls, and will often take part in streetside shows that will include audience participation.
Today, guests are treated to a wide array of characters and performers, many of which make their only Walt Disney World appearances at Disney's Hollywood Studios. Some examples include characters from JoJo's Circus, Little Einsteins and Kim Possible. Similarly, characters from new Disney and Pixar animated features will make their Walt Disney World debuts at the park, such as those from Meet the Robinsons and Pixar's Ratatouille. Live musical acts, such as the cover band Mulch, Sweat and Shears and the a cappella quartet Four For a Dollar, will perform on the park streets or as pre-show entertainment at the larger shows.
Like the Magic Kingdom and Disney's Animal Kingdom parks, Disney's Hollywood Studios also runs daily parades down Hollywood Boulevard. The "Pixar Block Party Bash" parade features Pixar film characters performing in a street party along Hollywood Boulevard and near Echo Lake. Several times each day, the "High School Musical 3 S
enior Year : Right Here Right Now" show will travel Hollywood Boulevard before performing a live street show in front of the Sorcerer's Hat.

Production history
The Walt Disney Company's original concept of the Disney-MGM Studios was to operate it as a full fledged television and motion picture production facility, not just a theme park. In 1988, among the first feature-length movies filmed at the facility, prior to its completion and opening as a theme park, were Ernest Saves Christmas and Newsies. When the park opened in 1989, the studio/production facilities housed two major components, the first of which was Walt Disney Feature Animation Florida, where Disney produced a number of projects, including Mulan, Lilo & Stitch, Brother Bear, and sequences from other 1990s-early 2000s Disney animated features. The second, larger, component was Walt Disney Studios Florida, which consisted of three sound stages used for various Disney projects including The Disney Channel's Mickey Mouse Club and Adventures in Wonderland. Several third party productions also used the Studios, including Superboy (first season only, from 1988-1989), Thunder in Paradise, a revival of Let's Make a Deal, special broadcasts of Wheel of Fortune and airplane interior sequences for the feature film Passenger 57. In addition, a number of music videos and several tapings for World Championship Wrestling (as well as live broadcasts of WCW Monday Nitro) were also shot there. Even The Post Group had a Florida-based post-production facility located on the Studio lot throughout the 1990s. All these production and post-production facilities were constructed to be an integral part of the theme park's Backstage Studio Tour as well.
During the closing credits of the Mickey Mouse Club (later, MMC in its final seasons) and Adventures in Wonderland, the lit Disney-MGM water tower appeared on the screen and one of the cast said, "(insert show title here) was taped at the Disney-MGM Studios at the Walt Disney World Resort in Orlando, Florida." Disney management (including CEO Michael Eisner) decided to downsize Disney's Florida operations by closing the animation studio, laying-off personnel and then moving the operations to the main animation studio in Burbank, California.
A radio studio is also located on the lot, appropriately behind "Sounds Dangerous". It originally housed the first children's radio network Radio Aahs which rented the studio. Later, Disney founded Radio Disney and essentially drove Radio Aahs out of business. Radio Disney decided it was no longer profitable to operate in Florida so they moved all of their shows from the Disney-MGM Studios to the Radio Disney headquarters in Dallas, Texas and the once bustling Disney Studios Florida radio studios are now used as remote studios for radio shows that are visiting Disney or the Orlando area and need a broadcast facility.
MGM litigation
In 1985, Disney and Metro-Goldwyn-Mayer entered into a licensing contract that gave Disney worldwide rights to use the MGM name and logo for a yet-to-be-built backlot studio theme park.
Disney's plans for what became the Disney-MGM Studios theme park at Walt Disney World Resort included working production facilities for movies and television shows and a satellite animation studio, which began operation prior to the park's debut. In 1988, MGM/UA responded by filing a lawsuit that claimed Disney violated the 1985 agreement by operating a working movie and television studio at the Florida resort.
In 1989, the theme park opened adjacent to the production facilities as the Disney-MGM Studios. The only affiliation MGM had to the park was the original licensing agreement that allowed Disney to use the MGM brand name and lion logo in marketing, plus separate contracts that allowed specific MGM content to be used in The Great Movie Ride.
Disney later filed a countersuit, claiming that MGM/UA and MGM Grand, Inc. had conspired to violate Disney's worldwide rights to the MGM name in the theme park business and that MGM/UA would harm Disney's reputation by building its own theme park at the MGM Grand hotel and casino in Las Vegas, Nevada.
On October 23, 1992, Los Angeles Superior Court Judge Curtis B. Rappe ruled that Disney had the right to continue using the Disney-MGM Studios name on film product produced at the Florida facility, and that MGM Grand had the right to build a Las Vegas theme park using the MGM name and logo as long as it did not share the same studio backlot theme as Disney's property. The 33 acre MGM Grand Adventures Theme Park opened in 1993 at the Las Vegas site and closed permanently in 2000.
Disney was contractually prohibited from using the Disney-MGM Studios name in certain marketing contexts like the free Walt Disney World vacation-planning kit; in those instances the park was called The Disney Studios.
Name change

The Florida resort later announced that the new name would be effective January 7, 2008, adding that it would take several more months to change all affected signage.
Former attractions:
Walt Disney Studios Park
Disney's Hollywood Studios has a sister park at the Disneyland Resort Paris called Walt Disney Studios Park. Originally, a Disney-MGM Studios Europe was to open in 1996, but plans were scrapped when the resort underperformed. Plans for a film-themed park were revived when the resort finally made a profit in 1995.
The two parks share the same basic theme (the entertainment industry) and have provided attractions to each other. The French park debuted with a Backlot Tour that included a version of Catastrophe Canyon, and a re-themed version of Florida's Rock N Roller Coaster. For the Happiest Celebration on Earth in 2005, a state-side version of Walt Disney Studios' popular auto stunt show was built at the Florida park, now known as Lights! Motors! Action!.
