Are there any sites where I could find out who won past Academy?!
Question: Awards dating back at least ten years?
Answers: Awards dating back at least ten years?
IMDB.com has an entire section for past Academy Award winners and nominees. On the main page, scroll down and at the left you'll see "Award Winners." This leads you to a page for major awards. Click on Academy Awards and a huge list of every Oscar year will show up. Clicking on each year will give you the nominees and winners of that year. Hope that helped!
