Miss Universe 2010 National Costume Show

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.
In 2003, the Top 15 was again selected instead of the Top 10. Cuts were made to make the Top 10, and eventually the Top 5. The final question varied, each coming from the final delegates themselves and the current Miss Universe.
In 2006, twenty semi-finalists were announced, with these delegates competing in the swimsuit competition. The number of competing delegates was then cut to ten, with those delegates competing in the evening gown competition. After that round of competition, the final five were announced, with the finalists competing in the "final question" or interview round. At the end of competition the runners-up were announced and the winner crowned by the outgoing queen.
