History: Miss Universe Winners 1952-2010

From 1959 to 1964, there were slight format changes. In 1959 through 1963, there was no cut to 5 finalists; the runners-up and winners were called from the assembled 15 semi-finalists. In 1964, the top 15 became a top 10, and after a round of interview, the winner and runners-up were called from the 10 finalists.
In 1965, the pageant returned to the original format of a cut to 5 finalists, and remained so until 1989.
In 1969, a final question was posed to the last five contestants. The final question was an on-and-off feature of the pageant. In 1990, it had taken root and every pageant since, the final contestants have to answer a final question.
