The Triple Crown is the pinnacle of American horse racing. It consists of three races in five weeks for 3-year-old thoroughbreds: Kentucky Derby, Preakness Stakes, Belmont Stakes. Only 13 horses have won all three.
The Belmont Stakes started in 1867, followed by the Preakness in 1873, and the Kentucky Derby in 1875. Sir Barton was the first to win all three in 1919 but the term "Triple Crown" wasn't popularized until the 1930s. CBS pioneered Triple Crown broadcasting, airing the Belmont Stakes in 1948 and the Preakness in 1949, before adding the Derby in 1952. By the 1960s, the Triple Crown was a national spectacle, fueled by expanded TV access and improved production.
The series is now a cultural event, and the most visible events in horseracing. The Kentucky Derby, in particular, is a major television event known for its traditions—including elaborate hats, mint juleps, and singing of "My Old Kentucky Home"—and significant betting. The 2025 event saw a record $349M in bets and was watched by an average of 17.7 million people, the most since 1989.
