In the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger , Franco Columbu , Lou Ferrigno , and others in the 1977 docudrama Pumping Iron . By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion ,  who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America, and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
Known for being long time bodybuilding rival of Arnold Schwarzenegger and the original Hulk on the TV show, Lou Ferrigno was also a deputy graduating from Brooklyn Technical High School in 1969, Ferrigno won his first major titles, IFBB Mr. America and Mr. Universe, four years later. In 1974, he came in second on his first attempt at the Mr. Olympia competition. He then came third the following year, and his attempt to beat Arnold Schwarzenegger was the subject of the 1975 documentary Pumping Iron. Following this, Ferrigno left the competition circuit for many years, and went for his acting career.
