Walmart began in 1945 as a Ben Franklin franchise owned by Sam Walton and family. In the 1960s, Walton started his first discount store but faced competition. By the 1980s, Walmart was one of the most successful retailers in America with annual sales growing from $1 billion in 1980 to $26 billion in 1989. In 1987, Walmart implemented two new concepts: hypermarkets selling everything including food, and supercenters which were scaled down hypermarkets. Walmart's key competitive advantages included low prices, large number of stores, wide product variety, strong vendor relationships, and efficient communications and logistics networks.
