A century ago, it was one of the biggest names in retail. Now, even Sears officials say its future could be in doubt — though they say they have plans to make sure the retail icon survives.

Nancy Koehn with the Harvard Business School says that in its early days, Sears Roebuck and Co. was like Amazon is today — a retailer of great disruption.

For Sears, it meant a path-breaking strategy of offering all sorts of merchandise in catalogs and building department stores in remote places with ample parking.

"It wasn't the Internet, but it was the same idea that no matter where you are you can touch and feel and imagine what these different products could mean in your life by virtue of an outreach, a distribution channel that an imaginative and gutsy retailer — in this case Sears — had created and then invested in and then enlarged," Koehn says.

Elgin, Ill., about 40 miles northwest of Chicago, is one town where Sears' innovation is clearly visible. Drive through the streets of one neighborhood and more than likely there will be a Sears Roebuck mail-order kit house on one of the lots.

Dr. Rebecca Hunter, an architectural historian, stands on the porch of one of them — an Arts and Crafts-style bungalow listed as "The Osborne" in the Sears catalog. It's one of about 200 Sears homes in Elgin.

"It's a phenomenon that gained popularity in the 1920s," Hunter says. "Mostly your framing boards were cut at the mill and numbered so that your builder would know how to put them together."

Between 1908 and 1940, Sears sold blueprints and approximately 70,000 pre-cut kit houses. It was a small part of the company's booming business. Sears' stature is far smaller these days amid a constantly changing retail landscape that brought with it the dominance of Amazon, the rise of e-commerce and big-box discount retailers.

It has left brick-and-mortar stores reeling. Despite its merger with Kmart in 2005, Sears has consistently lost millions of dollars each quarter.

The retailer has closed hundreds of stores, slashed jobs and sold off key assets like the Lands' End clothing line and its legendary Craftsman brand — although both brands continue to be sold at Sears. Independent retail analyst Sucharita Mulpuru says these changes haven't worked.

"There are just so many onerous forces relating to competition," she says. "I think that no matter what they do, they are fighting a losing battle."

In a memo, CEO Eddie Lampert says Sears is taking decisive action to return to profitability and to become a new kind of retailer. Some analysts accuse Lampert of sucking the value out of the company, selling off its most marketable assets. Then there's that line in Sears' recent annual report to federal regulators that states " substantial doubt exists related to the Company's ability to continue as a going concern."

But Leena Munjal, a Sears senior vice president in charge of retail operations, says reports of the company's demise are exaggerated.

"Do we have challenges? Absolutely," she says. "Just like many of the retailers out there and we are all trying to figure out what are the changes we need to make to our business models to be able to rise to those challenges."

Sears' transformation plan includes a membership program called Shop Your Way. Customers collect points they can redeem when they shop at Sears. The company has also worked on ways to make it more convenient for customers to shop online, or on their phones.

The Sears at Woodfield Mall, about 30 miles northwest of Chicago, is huge. There are clothes, fitness equipment and aisles of gleaming appliances. Carla and Jeremy Lang push their twin 18-month-old sons in a stroller while looking at ovens and stoves. Carla Lang says they've heard about the store's financial troubles.

"We've read stuff online that they may be closing stores and whatnot, but we still come here," she says. "It's close by, and like I said we've had success with purchasing things."

There are others though, loyal past shoppers, who haven't been in a Sears for years. Susan Mullen has fond memories of the store but says she's not sure Sears' efforts to transform itself will work.

"It fits no niche. It's not a discount place. It's not high end," Mullen says. "It has no identity anymore. I guess it tried to be everything to everybody and it was very successful at that. But now it's nothing to nobody, which is sad."
