: Astroturfing Leonardo: New "Information Campaign" for Diamonds

September 4, 2006 11:17 AM - Lloyd Alter, Toronto

Leonardo DiCaprio's new movie The Blood Diamond, opening in December, takes place in Sierra Leone in the late '90's and evidently takes a dim view of conflict diamonds. In anticipation, the ever-vigilant World Diamond Council has set up a new website to set the record straight before Leonardo, um, confuses us. “We’ve intensified our efforts because of this upcoming movie,” [President, WDC] Mr. Izhakoff said. “We wanted to make sure that retailers and consumers get the facts about the good things that diamonds do.” The NY Times compares this to our favourite astroturfing campaign from the Competitive Enterprise Institute, but this one isn't funny at all. ::Diamond Facts via ::New York Times
