That show helped prompt Apple to release, for the first time, a list of its suppliers and allow outside audits of working conditions at its suppliers. (Discussed here on a previous Slashdot story.)
This American Life has now retracted the episode after finding out that Mike Daisey, whose visit to the factory the show was based on, fabricated portions of the story. This included a number of minor items, but also major ones such as his saying that he personally met underage workers and those poisoned by hexane exposure.
To set the record straight, this weekend's episode of This American Life will present how they were mislead into airing a flawed story.
