Academy Award Nominations

Winners had been announced three months earlier of their triumphs; however that was changed in the second ceremony of the Academy Awards in 1930. Since then and during the first decade, the results were given to newspapers for publication at 11 pm on the night of the awards. This method was used until the Los Angeles Times announced the winners before the ceremony began; as a result, the Academy has used a sealed envelope to reveal the name of the winners since 1941.
For the first six ceremonies, the eligibility period spanned two calendar years. For example, the 2nd Academy Awards presented on April 3, 1930, recognized films that were released between August 1, 1928 and July 31, 1929. Starting with the 7th Academy Awards, held in 1935, the period of eligibility became the full previous calendar year from January 1 to December 31.
The first Best Actor awarded was Emil Jannings, for his performances in The Last Command and The Way of All Flesh. He had to return to Europe before the ceremony, so the Academy agreed to give him the prize earlier; this made him the first Academy Award winner in history. The honored professionals were awarded for all the work done in a certain category for the qualifying period; for example, Emil Jannings received the award for two movies in which he starred during that period. Since the fourth ceremony, the system changed, and the professionals were honored for a specific performance in a single film. As of the 83rd Academy Awards ceremony held in 2011, a total of 2,809 Oscars have been given for 1,853 awards. A total of 302 actors have won Oscars in competitive acting categories or been awarded Honorary or Juvenile Awards.
The 1939 film Beau Geste is the only movie that features as many as four Academy Award winners for Best Actor in a Leading Role (Gary Cooper, Ray Milland, Susan Hayward, Broderick Crawford) prior to any of the actors receiving the Best Actor Award.
