During the 1980s, KO Magazine, nicknamed "The knockout boxing magazine", ran some popular features, such as a round-by-round section where the most important fights were described punch by punch, posters with the boxer's complete records on the back and a question and answer interview section.
During the 1990s, KO Magazine was acquired by London Publishing, becoming a sister of old rival The Ring.
In September 2007, KO Magazine was acquired by Golden Boy Enterprises, along with The Ring.
