It was first held in 1985, and was held annually in December through 2006. Beginning in 2007, the meet's first-weekend-of-December timing was given over to the resurrected USA Short Course Nationals, and the U.S. Open moved to being held on an as-needed basis. Since 2007, the meet has been held in early August, in years where the U.S. Nationals are not held in August.
The United States Swimming National Championships are held annually, in summer. The event is organized by USA Swimming, and is held in a long course (50m) pool. In the past, and as recently as 2007, there were 2 meets annually: a Spring and a Summer Nationals. The Spring meet began as a 25-yard meet, while the Summer meet was long course. Prior to USA Swimming's creation in the late 1970s, the meet was run by the AAU.
