During the late 1960s, Tyson Foods was devising new methods to broaden their market, including introducing smaller consumer packaging and landing military contracts. The company expanded its commercial division by offering new products to McDonald's and Burger King. Tyson's McDonald's product eventually evolved into Chicken McNuggets while Burger King's product became the basis of its chicken sandwiches. For their 2010 rib promotion, Tyson was Burger King's pork supplier. Despite a production-significant lead time, the estimated four-month product supply lasted Burger king less than three months.
