Brownie Wise and Tupperware

A very interesting story of a change agent: Brownie Wise was a brilliant salesperson who caught the eye of Earl Tupper and helped create the concept of Tupperware Parties, a major paradigm shift in marketing and sales. Her story is relatively obscure due to various circumstances, which actually make the entire case more appealling and suitable for analysis.
I was given this example by Rosaura Aguilar Cruz, a student in my Innovation class. Here is an excerpt of the source:

"Modeled on the home party plan pioneered by Stanley Home Products and expanded and refined by Brownie Wise, the home party plan became and remains the exclusive outlet for Tupperware." http://americanhistory.si.edu/archives/d8470b.htm
