In the mid-1990s, the initial era of the supermodel ended and a new era for the supermodel began driven by heroin chic. By the late 1990s, actresses, pop singers, and other entertainment celebrities began gradually replacing models on fashion magazine covers and ad campaigns. The pendulum of limelight left many models in anonymity. A popular "conspiracy theory" explaining the supermodel's disappearance is that designers and fashion editors grew weary of the "I won't get out of bed for less than $10,000 a day" attitude and made sure no small group of models would ever again have the power of the Big Six.
