The land on which the Sears Tower stands was initially owned by Comcast before being sold to Ted Turner, who then sold various TV networks he owned.
The Willis Tower (formerly and informally: Sears Tower, its name until 2009) is a 110-story, 1,450-foot (442.1 m) skyscraper in Chicago. Sears purchased 15 old buildings from 100 owners and paid $2.7 million to the City of Chicago for the portion of Quincy Street the project absorbed.
