Kroc and the McDonald brothers fought for control of the business, as documented in Kroc's autobiography. The San Bernardino restaurant was eventually torn down in 1971, and the site was sold to the Juan Pollo chain in 1998. This area serves as headquarters for the Juan Pollo chain, and a McDonald's and Route 66 museum. With the expansion of McDonald's into many international markets, the company has become a symbol of globalization and the spread of the American way of life. Its prominence has made it a frequent topic of public debates about obesity, corporate ethics, and consumer responsibility.
