In the 1970s, bodybuilding had major publicity thanks to Arnold Schwarzenegger and the 1977 film Pumping Iron. By this time the IFBB dominated the sport and the AAU took a back seat.
This period also saw the rise of anabolic steroids both in bodybuilding and many other sports. To combat this, and to be allowed to be an IOC member, the IFBB introduced strict doping tests for both steroids and other banned substances.
