Baudrillard points to a number of phenomena to explain this loss of distinctions between "reality" and the simulacrum:
Contemporary media (television, film, magazines, billboards, the Internet) are concerned not just with relaying information or stories but with interpreting our most private selves for us, making us approach each other and the world through the lens of these media images. We therefore no longer acquire goods because of real needs but because of desires that are increasingly defined by commercials and commercialized images, which keep us at one step removed from the reality of our bodies or of the world around us.
