'The Blair Witch Project' is the ultimate 'indie-to-blockbuster' success story. Produced for roughly $60,000, it grossed nearly $250 million. Its success was driven by the world's first major viral internet marketing campaign. The filmmakers created a website featuring fake police reports and interviews about 'missing' students, leading many early internet users to believe the 'found footage' was real. This blurred the line between fiction and reality, proving that a massive marketing budget wasn't necessary if you had a compelling, mysterious hook that people wanted to share online.
