Sports Illustrated (SI) is an American sports magazine owned by Authentic Brands Group, and was first published in August 1954.

It was the first magazine with circulation over one million to win the National Magazine Award for General Excellence twice. It is also known for its annual swimsuit issue, which has been published since 1964, and has spawned other complementary media works and products.

In 2018, the magazine was sold to Meredith Corporation by means of its acquisition of parent company Time Inc., but Meredith stated that it planned to sell Sports Illustrated as it did not align with its lifestyle properties. The following year, Meredith announced that it would sell Sports Illustrated to Authentic Brands Group. While Meredith initially planned to continue publishing its print and digital properties under license from ABG (who planned to leverage the Sports Illustrated brand in other markets), ABG later announced that it would instead give the publishing rights to theMaven, Inc.—a digital media company.
