The official website for the Oscars maintains a list of all nominees and winners for the most recent awards ceremony. Additionally, Oscars.org, FilmSite.org and Deadline.com all maintain lists of current and past winners in various categories.
Go.com, which is owned by the ABC network, posts the full list of Oscar nominees each year on the section of the site dedicated to the awards ceremony. After the ceremony broadcast, the page is updated to include the winners from that year. The site also contains information about the winners, the host and the different nominees, as well as clips from the broadcast after it airs. Deadline.com also publishes a list of nominees that is updated with a full list of winners once the awards show airs. The site also preserves the list for each year so that users can view past winners.
Oscars.org hosts a comprehensive database of all the Academy Awards winners for each year since the ceremony started in 1929. The site includes the full list of nominees for each category and pictures or video, when available, of the winners. The awards section is organized by decade and then by year, allowing users to easily navigate to a specific ceremony.
