for commercial purposes, or demolition. Opposition to the towers on Times Square, along with Prudential and Park Tower's inability to secure tenants for the proposed buildings, led government officials to allow Prudential and Park Tower to postpone the project in 1992. By then, Prudential had spent $300 million on condemning the sites through eminent domain. The partners retained the right to develop the sites in the future, and the ESDC's zoning guidelines remained in effect. In exchange for being permitted to delay construction of the sites until 2002, Prudential and Park Tower were compelled to add stores and install large signage on the existing buildings. In 1992, the Times Square Alliance (formerly the Times Square Business Improvement District, or "BID" for short), a coalition of city government and local businesses dedicated to improving the quality of commerce and cleanliness in the district, started operations in the area. In 1998, the alliance opened a tourist information center in the former Embassy Theatre at 1560 Broadway; the information center operated until 2014. In the mid-1990s, Mayor Rudolph Giuliani led an effort to clean up the area, an effort that is described by Steve Macek in Urban Nightmares: The Media, the Right, and the Moral Panic Over the City: Security was increased, pornographic theatres were closed, and "undesirable" low-rent residents were pressured to relocate, and then more tourist-friendly attractions and upscale establishments were opened. Advocates of the remodeling claim that the neighborhood is safer and cleaner. Detractors have countered that the changes have homogenized or "Disneyfied" the character of Times Square and have unfairly targeted lower-income New Yorkers from nearby neighborhoods such as Hell's Kitchen. The changes were shaped in large part by the actions of The Walt Disney Company, which bought and restored the New Amsterdam Theatre after several attempts at redevelopment had failed. As part of a contract with Disney, officials from the city and state evicted the pornographic theaters and contracted with Madame Tussauds and AMC Theatres to move onto 42nd Street. This spurred the construction of new office towers, hotels, and tourist attractions in the area. Prudential and Klein dissolved their partnership for the four office-building sites at Times Square's southern end in 1996. The same year, Douglas Durst acquired the site at the northeast corner of Broadway and 42nd Street, and he developed 4 Times Square there. The northwest corner of Seventh Avenue and 42nd Street was taken
