From modest beginnings as a tea shop, the Great Atlantic & Pacific Tea Company became the largest retailer in the world. It was a juggernaut, with nearly sixteen thousand stores. But its explosive growth made it a mortal threat to mom-and-pop grocery stores across the nation. Main Street fought back tooth and nail, leading the Hoover, Roosevelt, and Truman administrations to investigate the Great A&P. In a remarkable court case, the government pressed criminal charges against the company for selling food too cheaply-and won. In The Great A&P and the Struggle for Small Business in America, the acclaimed historian Marc Levinson tells the story of a struggle between small business and big business that tore America apart. George and John Hartford took over their father's business and reshaped it again and again, turning it into a vertically integrated behemoth that paved the way for every big-box retailer to come. George demanded a rock-solid balance sheet; John was the marketer-entrepreneur who led A&P through seven decades of rapid changes. Together, they set the stage for the modern consumer economy by turning an archaic retail industry into a highly efficient system for distributing food at low cost. Now, with the internet reshaping retailing once more, concerns about the market power of giant retailers are again front and center. This second edition includes a new chapter exploring the controversies about Amazon and other online merchants in light of the history of the Great A&P.
