The original Star Wars hit theaters on May 25th, 1977.  Almost four decades later, the franchise is as popular as ever. An icon of pop culture, the Star Wars series has made a lasting impression on the toy industry, the clothing industry, and even the food industry. But perhaps the space saga's biggest influence is on the entertainment industry itself.

Are the Star Wars films the most referenced films of all time? Think about all the films and television shows that make mention of Star Wars characters, locations, vehicles, etc. Obviously, shows like The Big Bang Theory rely heavily on these types of references. But even acclaimed, prestigious films, like Boyhood, Boogie Nights, and Se7en, throw in Star Wars nods. Why is this? Why do so many filmmakers choose to reference the same films? It is widely believed that film and television serve as a mirror to society, meaning that our entertainment reflects our current culture. When was the last time you saw someone wearing a Star Wars shirt?  When was the last time you heard someone quote a famous line from the series? Yesterday? Today? Star Wars is a cultural phenomenon, and our entertainment reflects our own obsession. With a new entry, Rogue One, opening next week, the hype is greater than ever. In the meantime, here's a look at how the Star Wars franchise has invaded other films and television shows.
