I usually don't watch a lot of TV. But occasionally, when my roommates are watching something, I will sit down and watch for a while. The other day I came home to "How I Met your Mother." I was fascinated by how quickly I became aware that the entire premise of the show was premarital sex and how good it was. The other thing that surprised me was that the more I watched the show, the more tolerant I was of the idea of premarital sex. In fact, I found that, because the characters were funny, I almost got to the point of cheering them on when they hooked up with another sex partner. I don't know of any studies done about this topic, but I was a little astounded at how quickly I became "OK" with the idea of hooking up with a different complete stranger every night. It makes me wonder if shows like this are changing the perspective of their viewers.
