Tupperware

Tupperware was developed in 1946 by Earl Silas Tupper (1907–83) in Leominster, Massachusetts. He developed plastic containers used in households to contain food and keep it airtight. The formerly patented "burping seal" is a famous aspect of Tupperware, which distinguished it from competitors.

Tupperware pioneered the direct marketing strategy made famous by the Tupperware party. Brownie Wise (1913–92), a former sales representative of Stanley Home Products, developed the strategy. During the early 1950s, Tupperware's sales and popularity exploded, thanks in large part to Wise's influence among women who sold Tupperware, and some of the famous "jubilees" celebrating the success of Tupperware ladies at lavish and outlandishly themed parties. Tupperware was known—at a time when women came back from working during World War II only to be told to "go back to the kitchen, as a method of empowering women, and giving them a toehold in the post-war business world. The tradition of Tupperware's "Jubilee" style events continues to this day, with rallies being held in major cities to recognize and reward top-selling and top-recruiting individuals, teams, and organizations.
