stores, most Filene's and all the stores of nine other May-owned chains were renamed Macy's, the conversion officially occurred on September 9, 2006. Many Chicagoans resented the New York City brand replacing their local brand. Hundreds of protesters gathered under Marshall Field's famous clock that day, and returned on the one-year anniversary, September 9, 2007. Dozens attended "Field's Fans" rallies each anniversary from 2008 to 2012. Many Chicagoans felt betrayed by Macy's takeover of Marshall Field’s when the company began to change its aesthetics and customer service standards, and demoted many Chicago-based brands. In December 2006, Macy's reported 30% slower sales in former Marshall Field's stores; the focus shifted to promoting the State Street location in 2007. Renovations The Marshall Field and Company Building at State and Washington Streets in Chicago was listed on the National Register of Historic Places in 1978 and is part of the Loop Retail National Historic District. The building was designated a Chicago Landmark on November 1, 2005. With approximately two million square feet of available floor space, the building is the second-largest department store in the United States. In 1987, while under BATUS ownership, Field's State Street store underwent significant restoration. In 2004, while Field's was still owned by Dayton Hudson/Target, another extensive restoration of the landmark State Street store, costing $115 million, was begun; the last of the renovation was completed after the May acquisition. The 2004 renovations included the installation of new lower-level shops, removal of steel grates from the upper portions of the store's historic light wells, and the addition of an eleven-story atrium in what had been an alley and mid-store light shaft. In 2004, Field's also introduced significant upgrades to merchandise and the introduction of luxury vendor relationships, in which 10% of the floor space was leased to outside vendors in a manner similar to Selfridge's in London (Selfridge's was founded by former Field's executive Harry Selfridge, who based his business model on Marshall Field's; likewise, the Selfridge's building in London was based on the architecture of the Marshall Field's store). Firsts, noted events, community leadership Among the "firsts" by Marshall Field's was the concept of the department store tea room. In the 19th century, ladies shopping downtown returned home for lunch; having lunch at a downtown restaurant unescorted by a gentleman was not considered ladylike. But after a Marshall Field's clerk shared her lunch (a chicken pot pie)
