Sports Illustrated is the largest weekly American sports magazine owned by media conglomerate Time Warner. It has over 3 million subscribers and is read by 23 million adults each week, including over 18 million men, 19% of the adult males in the country. It was the first magazine with circulation over one million to win the National Magazine Award for General Excellence twice.

Its swimsuit issue, which has been published since 1964, is now an annual publishing event that generates its own television shows, videos and calendars.

The magazine's cover is the basis of a sports myth known as the Sports Illustrated Cover Jinx.
