One of Chicago’s signature towers loses its John Hancock

Chicago’s fourth tallest building will no longer be known as the John Hancock Center, as the insurance company that built the 100-story tower in the 1960s asked that its name and logos be removed from the structure. Hearn Co., which owns the tower, will refer to it as 875 North Michigan Avenue, the building’s address, until a new deal can be struck for naming-rights, CEO Stephen Hearn told the Chicago Tribune. John Hancock hasn’t been a tenant in the building for many years. [Chicago Tribune]
