These days Mike Daisey is run off his feet. "I don't even have time to listen to my voicemail now. That's a phenomenon I have not experienced before," he said with an amazed laugh.
He shouldn't be so surprised. In the past fortnight, Daisey has gone from being a gifted but obscure solo act in the United States theatre to the public face of a backlash against one of the iconic corporations of the 21st century.
Daisey's latest work, The Agony and the Ecstasy of Steve Jobs, has triggered a spasm of soul-searching about the sometimes appalling labour conditions in China under which many of America's most cherished products are made. Specifically, the shiny, sleek iPhones, iPods and iPads produced by Apple.
The Agony and the Ecstasy was devised after exhaustive research talking to exploited and abused workers in China for almost 18 months. Daisey played to small but appreciative crowds across the US, winning critical praise but stirring little trouble, not even with the target of his ire: Apple itself.
But everything changed last month when a discussion and partial performance of Daisey's monologue appeared on the National Public Radio show This American Life. It rapidly became the most downloaded episode of the show's history and an online petition calling for Apple to reform its practices began. Within 48 hours it attracted 140,000 names. Then the New York Times ran an exhaustive investigation of Apple's supplier network in China that revealed industrial accidents, brutal working conditions and child labour. Suddenly, Apple's Chinese supplier network was huge news.
