Feminist theory was influenced mainly by women studies, and second wave feminism. The latter movement was revolutionary, mainly with the concept of women taking center lead rather than just being considered an ‘other’ to men. French writer Simone de Beauvoir looked into this concept during the late 1940’s, citing in her 1949 book ‘The Second Sex’: male centered sociology was accepted as the norm. This reinforced the idea that the society was socialized into believing men were superior because society had centered around them at the time.
Inspired by the work of Beauvoir, feminist Betty Friedan objected to the depiction of women in the media and argued that women who just stayed at home were typically unhappy. This popular view spread the movement faster, leading to the need for strong, inspirational female characters to backup the popular ideas
