One of the world's most iconic skyscrapers has long-tempted Chicago visitors to squint, crane their necks and try to see the tip of America's tallest building. But starting Thursday, the Sears Tower will be gone.
Its black, block-like architecture and towering rooftop spikes will remain, but the widely recognized name it carried for three decades will be pushed out by a British company.
Willis Tower was to be introduced to Chicago by Mayor Richard M. Daley and others on Thursday during a public renaming ceremony hosted by Willis Group Holdings. The London-based insurance brokerage secured the naming rights as part an agreement to lease 140,000 square feet of space on multiple floors of the building, and has said it plans to bring hundreds of jobs to the city.
But some locals aren't sold.
"It's always going to be the Sears Tower. It's part of Chicago and I won't call it Willis Tower. In Chicago we hold fast,"Chicago teacher Marianne Turk, 46, said as she stood in line this week to go up to the building's Skydeck.
And she's not alone. On the Web site Searstower.org, 88 percent of responders say they'll continue to refer to the building as Sears Tower.
"Early Show" co-anchor Maggie Rodriguez said on the broadcast Thursday, the name will likely stick "forever and ever and ever."
The 110-story skyscraper has been known as Sears Tower since it opened in 1973. Its original tenant, Sears Roebuck and Co., moved out in 1992 but its sign stayed. The company's naming rights had expired in 2003, but it continued to be called the Sears Tower. A real estate investment group,
American Landmark Properties of Skokie, now owns the 1,450-foot-tall building.
"Everybody knows that tower," Willis Group Holdings chief executive Joe Plumeri said ahead of Thursday's ceremony. "If we're good corporate citizens and do what we should, hopefully Willis and the tower and Chicago will all become synonymous."
Historically, skyscrapers have been businesses unto themselves, acting as a commodity to compete for high rents and tenants, said Carol Willis, founder and director of The Skyscraper Museum in New
"Naming rights are an asset of the building. They can be turned into money and that's what the new owners are doing," she said.
Other well known buildings have undergone name changes - New York City's Pan Am Building became the MetLife Building, and Chicago's Standard Oil Building is now the Aon Center - but the public hasn't always taken to them.
"Early Show" co-anchor Harry Smith said Avenue of the Americas, which refers to Sixth Avenue in New York, hasn't ever stuck.
"It's Sixth Avenue," he said.
The Chicago tower's owners acknowledge it will take time for some people to accept the new name, but they're confident it will happen eventually.
"It is an icon, but I believe over time it will become known as Willis Tower," said John Huston of American Landmark Properties, who represents the building ownership.
"Early Show" weather anchor and features reporter Dave Price said it takes a generation of people to forget the old name for the new one to finally find its way into the mainstream.
Alex Lucas, 29, an Arlington Heights business systems analyst who works down the street from the skyscraper, was so displeased with the name change that he started a Web site, www.itsthesearstower.com.
"Chicago is going to lose a big part of what is its identity and I don't know what's going to fill that space," Lucas said.
The new name isn't the only major change this year. Last month, owners announced a $350 million greening effort, complete with wind turbines and solar panels, along with plans for a 50-story luxury hotel.
For tourists, glass-bottomed enclosed balconies on the 103rd Skydeck were opened earlier this month, giving visitors a 1,353-foot (412-meter) look straight down.
However, all these efforts were part of a plan aimed at remarketing the building as a pioneer and reintroducing it to the world, owners say.
And it may be working. Rodriguez said she'd like to visit the Skydeck, and maybe even do "The Early Show" there someday.
Reluctance to let go of the name is understandable, said Plumeri, Willis Group Holdings' CEO. But, he added, "By the same token life moves on, nothing ever stays the same. Chicago is an evolving city."
