Earl Tupper founded Tupperware in 1938 and created the first Tupperware products from polyethylene. Brownie Wise introduced the direct sales "party plan" method in the late 1940s which removed products from retail and had women sell through home demonstrations, fueling the company's success. Tupperware tailored products to consumers and expanded globally, entering India in 1996 where it grew rapidly through its direct sales model focused on women distributors and customers.
