The Tupperware party was good while it lasted. We take the benefits of Tupperware for granted, but it was a significant innovation in its time, one that we should be grateful for, says Megan McCardle. “As with so much in life, the strategies that made Tupperware a success in the 20th century also made it hard for the company to adapt to the 21st.” Maybe true, but these days, when a consumer brand fails, my first thought is to blame financial shenanigans rather than business execution.
