Disney, while typically embracing a more "traditional" prince/princess model, has slowly been creeping into the 21st century by introducing characters with more modern traits. Frozen showcased a woman out to save herself instead of being rescued by a man. Maleficent gave us the backstory that Sleeping Beauty left out, giving us a whole new perspective of the "evil" witch. And Big Hero 6 intrigued us with Disney's first Japanese-American characters.
Now, Disney's crossing into new (for them) territory - they are introducing a gay storyline in the 2017 live action version of Beauty and the Beast starring Emma Watson.
