What film is noted for revolutionizing Internet-based promotion?

The Blair Witch Project is noted for revolutionizing Internet-based promotion due to its innovative marketing strategy that harnessed the power of the internet in a way that was unprecedented at the time of its release in 1999. The film's creators used online platforms to create a sense of authenticity and realism around the movie's premise, which was essential to its appeal. They developed a website that included fake documentary-style content and backstory, presenting the film as a real-life event. This approach generated significant buzz and curiosity among audiences, who were drawn in by the concept of a "found footage" horror story.

This marketing campaign effectively transformed how films were promoted, leveraging the internet's ability to spread information quickly and engage potential viewers directly. The success of The Blair Witch Project demonstrated that a low-budget film could achieve massive box office returns through clever and effective online marketing, setting a precedent that many filmmakers have followed since. This usage of the internet for promotion and audience engagement made The Blair Witch Project a landmark in the history of film marketing.
