History

The South of Market Area where Moscone Center was built was claimed by the
San Francisco Redevelopment Agency
The San Francisco Redevelopment Agency (SFRA) was an urban renewal agency active from 1948 until 2012, with purpose to improve the urban landscape through "redesign, redevelopment, and rehabilitation" of specific areas of the city.

, and a protracted battle was fought by the displaced low-income residents during the 1960s and 1970s.
Although the center is named after the murdered mayor, Moscone initially opposed the development of the area when he served on the SF Board of Supervisors in the 1960s because he felt it would displace elderly and poor residents of the area. As mayor, Moscone convened a special committee of proponents and opponents of a convention center. Hearings were held throughout SF seeking citizen input. A compromise was reached which was supported by Moscone. He put the matter on the ballot in November 1976 and it passed overwhelmingly.
The original Moscone Convention Center hall opened in 1981 on the site of what is now known as Moscone South. It was designed by a team at
Hellmuth, Obata & Kassabaum led by
Bill Valentine. The exhibition hall was placed underground to minimize the controversial convention center's visible footprint.
Moscone Center was featured in the 1995 movie ''
The Net'', with Sandra Bullock.
