Since Bunshaft’s addition opened in 1962, the art world has grown exponentially, diverging into a countless thematic streams and mediums, from monumental sculptures demanding monumental spaces to purely conceptual art requiring no space at all. The unpredictability of the art world and its growth into countless new disciplines demands a different kind of museum than Bunshaft or his contemporaries could have conceived. This uncertainty, coupled with a desire to reconnect with segments of the public long alienated from the art world, has driven expanding museums to favor vast public spaces and highly adaptable galleries over the more intimate spaces of the past.
