No more Sears Tower?!?!

This is so not right:

The world-famous Sears Tower in Chicago is getting a new name.
The 110-story building will be named Willis Tower —
to reflect the name of the building’s new lessee, Willis Group Holdings.
The London-based insurance broker plans to move five of its offices and about
500 employees into the tower.
Sears Roebuck and Company has not occupied the building since 1992.
The tower was once the tallest building in the world —
now it’s the tallest in the Western Hemisphere.
