The 1970s saw a very different kind of worry develop with regards to pornography. In the peak of the feminist movement, people began voicing concerns about the objectification of women in porn. While some may argue that not all porn objectifies women, there is a pretty straightforward reason why most does. "You have a heterosexual male consumer base which is raised in a male-dominant society…what would you predict would be the development of the pornography industry given those two facts?" says Robert Jenson, professor in the school of journalism at the University of Texas at Austin. Women also consume porn, but the biggest customer base was (and still is) men. So, porn catered to that demographic by creating products that often subjugated the women involved.
