Granted, Steven Spielberg’s suspense masterpiece didn’t exactly enact social change or help anyone (other than the studio’s shareholders), but it did change the world in one way – the nature of cinema, and how we consume it.

Indeed, Jaws was the inaugural blockbuster, the film that changed everything in popularising the big-budget cinematic spectacle. The film was a box office colossus, and defined the model that films of this type continue to follow today.

It was Jaws that helped to emphasise the feeling that if you weren’t seeing the big movie of the moment, then you were probably missing something. Just look at how Avatar managed to make almost $3bn – it’s because if you didn’t see it at the cinema, it was like you were missing a once in a lifetime event.
