of traditional gender roles for women of the future, with the women of the show's feminine behavior acting to reaffirm that women's sexuality and traditional femininity would not be lost. This fear was manifested by the media's criticisms of Valentina Tereshkova, the first female astronaut to go to space, as masculine and "mannish". The uniform's usage of the miniskirt was also considered progressive by some at the time, as the miniskirt, at that time, was a symbol of the modern woman's economic and sexual independence. Computer engineer and entrepreneur Steve Wozniak credited watching Star Trek and attending Star Trek conventions while in his youth as a source of inspiration for him co-founding Apple Inc. in 1976, which would later become the world's largest technology company by revenue and the world's third-largest mobile phone manufacturer.
