Walmart was founded in 1962 by Sam Walton and incorporated in 1969. It now operates over 6,600 stores worldwide. Walmart employs over 1.3 million people and is the largest public corporation by revenue. While some international expansions were unsuccessful, Walmart has found great success in operations across South America, China, Canada, and the UK. In India, Walmart entered a joint venture with Bharti Enterprises in 2007 to operate stores in the "Cash and Carry" format.
