Miss Universe 2010, Las Vegas, Nevada, United States

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.
In 1990, the pageant implemented major format changes in the competition itself. Instead of five finalists, the field was reduced from 10 semi-finalists to 6. Each contestant then randomly selected a judge and answered the question posed by the judge. After that, the field was narrowed down further to a final 3. In 1998, the number of finalists was reduced to 5, although there still was a cut to a final 3. This continued to 2001, where the final 5 format was re-instated.
In 2000, the interview portion of the semi-finals was quietly dropped and the contestants once again, as in the early days of the pageant, competed only in swimsuit and gowns.
