The toy revolution started with a girl named Rey.
Before "Star Wars: The Force Awakens" you would be hard pressed to find a female action figure on the shelves of your favorite toy store.
"[Disney] took a risk and they made a female the hero of 'Force Awakens'," Jim Silver, CEO of TTPM, an online toy review site, told CNBC. "She sold better than just about anyone, except for Kylo Ren, but the villain always sells better."
An accidental phenomenon, female action figures were never supposed to be big sellers. It's why in the last 20 years, it's hard to recall a best-selling action figure that was female.
"They never sold well so companies stopped making them," Silver said.
But the release of "The Force Awakens" in 2015, which pushed "Star Wars" toy sales for Hasbro to almost $500 million, changed that.
