This is a list of Academy Awards ceremonies.
This list is current as of the 89th Academy Awards ceremony held on February 26, 2017.
Beginning with the 7th Academy Awards, held in February 1935, each year's awards are presented for films that were first shown during the full preceding calendar year from January 1 to December 31 in Los Angeles County, California. For the first five ceremonies, the eligibility period spanned twelve months from August 1 to July 31. For the 6th ceremony, held in 1934, the eligibility period lasted from August 1, 1932 to December 31, 1933.
When citing each ceremony, Academy conventions may either list the year(s) of its eligibility period, or the year in which the ceremony was actually held.
Partial broadcast of the 11th Academy Awards ceremony was shut down after about ten minutes because KHJ did not have permission to broadcast live. (The radio host was whispering the names of the winners as they were announced, out of sight in the balcony.) Later in the evening, at the conclusion of the ceremony, KHJ broadcast a full announcement of winners, live from the ceremony venue, as per its original agreement with the Academy.
The 17th Academy Awards marked the first coast-to-coast broadcast of the ceremony, and first broadcast of the complete event. All subsequent ceremonies have been broadcast nationally in the USA. This was also the first ceremony in which film clips were used to introduce awards nominees.
The 40th Academy Awards ceremony marked the final year that the ceremony was simulcast live on the radio.
