What did saleswoman Brownie Wise popularize in the 50s?

Brownie Wise was a self-made woman who revolutionized marketing tactics and had a knack for motivating others. She introduced the now popular household item, Tupperware, to the market. A pioneering businesswoman when there were not many women in business, her career serves as an inspiration for generations of women. Tupperware was not selling well in the late 1940s and early 1950s. Wise, who saw promise in the product, began selling it with her mother in the late 1940s. The two began a direct selling business called Patio Parties. She adopted the home party technique she used at Stanley, throwing parties and demonstrating Tupperware mainly to women. She recruited dealers and managers and was soon selling more Tupperware than any store. In 1951, Tupper recruited Wise to develop the party plan model and made her Vice President of Marketing. After Wise took over marketing, millions of Tupperware began flying off the shelves.
