Here is a picture of the ending of Snow White and the Seven Dwarfs. It shows happiness and love. This ending is seen throughout every single disney film, because whats a princess without her prince and castle right? Wrong. The idea that to be a perfect women is to be happily married living in a large home has become very noticeable throughout modern day society.
For example Desperate housewives portrays life of the "everyday suburban" housewife. She's beautiful, lives in a large home and is happy on the outside yet not always on the inside. By creating problems in the TV show it brings the overly perfect lives of the characters a bit closer to reality making the audience feel like they have more of a connection to the people. This is a way in which Disney Princesses have influenced media and society today. They have raised the expectations of what the perfect women should be like.
