A time line depicting the impact of HIV/AIDS on the pornography industry can be divided into two segments. First was the pre-AIDS awareness era, roughly spanning the years up to 1988. During this period most of the adult film industry was in denial about HIV prevention, and most members of the industry refused to use their work as a means to explore the erotic dimensions of safer sex. However, attitudes began to change as the epidemic became entrenched in the public consciousness and performers began to fall ill and die. Most notable among the performers to develop AIDS was John Holmes, the quintessential porn star of the 1970s and 1980s, who continued to appear in films until his death in 1988, after testing positive for HIV in 1985.
