Most people don't watch films in the theater run exclusively. It has been viewed by many hundreds of millions of people after it left the box office. Also, network effects account for a lot. One person seeing the film and talking about blood diamonds to their friends and family leads to 2 others who look into it, which leads to 4 more, etc. That's how ideas spread.

It does not exist in a vacuum. I am not even arguing that the movie was irrelevant, but it was not that huge a deal and it was not the only voice in the discussion. The point in the parent was that ethics was not a driver because there was no inflection point when the movie was released, which to me is fallacious.

		He’s also just got his timing wrong. The movie came out when artificial diamonds were scarce and pricey. The technology accelerated after that, and the shifting mores could definitely have played a part.
