In 1948, Kordich contracted bladder cancer at twenty-five. A football star at University of Southern California, Kordich travelled across the United States to New York City to be treated by Dr. Max Gerson, who prescribed an all-juice diet. As a result, Jays life took a drastic turn for the better within only three months.
In 1989, he started his national television career, making appearances with his juicer, and by the end of 1990, Jay Kordich and juicing were widely known. His infomercials aired for over thirteen years. He used the “Juiceman” name for his own line of juicers, which included the Juiceman, Juiceman II, and Juiceman Jr. They were made available to consumers through infomercials, catalogs, and retail in the 1980s and 1990s.
