(A snippet from my PhD dissertation)
I consider postfeminism to mean after the height of the women’s liberation movement and the changes in society that it brought about. However, I am not trying to articulate a “style” of feminism. Rather, postfeminism offers a way of thinking through the way feminism has changed, and a way of marking and explaining a particular era – a specific generational moment.
As Joanne Hollows (2006: 104) articulates, today’s women:
“have grown up in conditions that are both shaped by second-wave feminism, and which are also the product of a time that is historically post-second-wave-feminism”. 
Avoiding the hyphenation, this is one sense in which I use the term postfeminism. It specifies the current historical moment, making clear the role cultural context plays in shaping a generation, and clarifies the extent to which feminism has impacted the lives of the current generation. The idea of “post” meaning “after” gets around the problem of envisaging it as “death”. It allows room to acknowledge that the young women today have grown up after the height of the second-wave women’s movement, in a cultural context different from their parents, that has been strongly influenced by second wave feminist discourses.
