Document 4: Mammoth Mart: Mammoth Mart was a discount department store chain, located in the northeastern United States, primarily in the New England area. The chain was founded by Max Coffman and Henry Gornstein in Framingham, Massachusetts in 1956, and was something of a prototype for the large, downscale department store, selling housewares, hardware and clothing in stark, unfussy buildings, usually in suburban shopping center locations. Other discount department store retailers like K-Mart, Zayre, and Bradlees would subsequently expand on this concept.
Document 5: Filene's: Filene's was an American department store, headquartered in Boston, Massachusetts; it operated throughout New England and in New York. It was owned by Federated Department Stores from 1929 until 1988, at which time it was acquired by The May Department Stores Company. In 2005, Federated Department Stores bought May Department Stores, which resulted in Federated reacquiring Filene's.

In the post-war years, the store became a regional chain in the eastern United States, and was last owned by Federated Department Stores. At the height of its existence, it had some 59 stores in 5 states. Formerly part of May Department Stores prior to that company's acquisition by Federated on August 30, 2005, Kaufmann's operated as part of the Filene's organization in Boston, Massachusetts. On February 1, 2006, the Filene's/Kaufmann's organization was dissolved and the management of its stores was assumed by Macy's East and the new Macy's Midwest. On September 9, 2006, Macy's retired the Kaufmann's name as Federated Department Stores converted the former May Company brands to its masthead. In 2015, Macy's closed and sold the iconic Pittsburgh store for redevelopment as part of the company's ongoing reorganization of its owned properties. Core Reality of Philadelphia, the new owners of the building, have named the proposed mixed-use property "Kaufmann's Grand on Fifth" in honor of the historic property.

The chain focused on buyout and closeout merchandise, and occasionally irregular apparel and factory seconds. The stores were branded Schottenstein's in the Columbus, Ohio, market and Valley Fair in the Northern New Jersey market. The Schottenstein name was dropped in 2008.

Document 9: Star Market: Star Market was a New England chain of supermarkets based in Greater Boston. It was owned by the Mugar family and started in 1915. The company was sold to The Jewel Companies, Inc. in 1964 and later to Investcorp, which in turn sold the chain to Shaw's Supermarkets. As stores were remodeled, many adopted the Shaw's name, leaving only a handful of Star Market stores operating by the late 2000s. In 2008, Shaw's began to revive the name, a trend which was expedited after the parent company of both chains was sold to Cerberus Capital Management. Today, both Shaw's and Star Market are administered as a single division.

Document 15: Downtown Norfolk, Virginia: Similarly, the advent of newer suburban shopping destinations spelled demise for the fortunes of downtown's Granby Street commercial corridor, located just a few blocks inland from the waterfront. Granby Street traditionally played the role as the premiere shopping and gathering spot in the Hampton Roads region and numerous department stores such as Smith & Welton (1898-1988), Rices Nachmans (1918-1985) and Ames and Brownley (1898-1973), fine hotels and theaters once lined its sidewalks. However, new suburban shopping developments promised more convenience and comfort. The opening of Pembroke Mall in Virginia Beach, the region's first climate controlled shopping mall, and JANAF Shopping Center in Norfolk's Military Circle area, helped foment Granby Street's spiral into commercial obsolescence. With amenities such as ample free parking at the door of one's favorite store, and in the case of Pembroke Mall, climate control, the businesses of downtown's Granby Street found it harder and harder to compete.
