Olympic Trivia: New traditions in 1932

At the first ten Olympic Games of the modern era, the medals were presented at the Closing Ceremony. But, at Los Angeles 1932 each victory ceremony took place shortly after the end of each event, a tradition that was adopted at subsequent Games and that has become a permanent feature.

Los Angeles also introduced the tiered victory podium on which the three medalists stand to receive their awards and was also the first Games to see the gold medalist honored with the raising of his national flag and the playing of their national anthem during the presentation.
