In 1997, MCI Communications released the "Anthem" advertisement, heralding the internet as a utopia without age, race, or gender. Lisa Nakamura argues in chapter 16 of her 2002 book "After/image of identity: Gender, Technology, and Identity Politics," that technology gives us iterations of our age, race and gender in virtual spaces, as opposed to them being fully extinguished. Nakamura uses a metaphor of "after-images" to describe the cultural phenomenon of expressing identity on the internet. The idea is that any performance of identity on the internet is simultaneously present and past-tense, "posthuman and projectionary", due to its immortality.
