CHICAGO, Illinois (CNN) -- Sears Tower is history. As of Thursday, the iconic Chicago, Illinois, skyscraper is now named Willis Tower.
At least that's what the owners of the 110-story skyscraper now call it after its new main tenant, the London, England-based insurance broker Willis Group Holdings. However, there are plenty of people who refuse to call it that.
More than 90,000 people have joined the group "People Against the Sears Tower Name Change," on the social networking Web site Facebook.
"This name change is absurd," one member wrote. "Would Paris change the name of the Eiffel Tower? Or London change Buckingham Palace? Or New York, the Statue of Liberty? I believe the Illinois Congress needs to proclaim the Sears Tower a recognizable landmark that is known all over the world by people who have traveled to Chicago."
