Introduction of World Trade Center
Unloved, unwanted, criticized and lambasted, the World Trade Center's two towers rose out of the New York City skyline in 1972 (tower one) and 1973 (tower two). Adding a million square feet of office space, they sat primarily empty over their first ten years, artificially filled with displaced employees of the Port Authority, which had overseen the original construction. Their pinnacle as the tallest buildings in the world (1,368 and 1,362 feet) lasted less than a year before being overtaken by the Sears Building in Chicago (1,454 feet).
