Sports Illustrated is an American sports media franchise owned by media conglomerate Time Warner. Its self titled magazine has over 3.5 million subscribers and is read by 23 million adults each week, including over 18 million men. 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.

Two other magazines named Sports Illustrated were started in the 1920s and 1930s, but they both quickly failed. Following these events, there was no large-base general sports magazine with a national following. It was then that Time patriarch Henry Luce began considering whether his company should attempt to fill that gap. At the time, many believed sports was beneath the attention of serious journalism and did not think sports news could fill a weekly magazine, especially during the winter. A number of advisers to Luce, including Life magazine's Ernest Havemann, tried to kill the idea, but Luce, who was not a sports fan, decided the time was right.
