Hollywood's motion picture academy will introduce new eligibility rules to boost diversity among Oscars nominees under a raft of new measures announced on June 12.
The move comes after years of criticism over a lack of diversity among the Academy of Motion Picture Arts and Sciences' members, and among the Oscar nominees and winners they select.
This year's historic Oscars were watched by the award show's smallest ever audience, with just 23.6 million viewers tuning in to ABC's domestic television broadcast.
The glitzy show in Hollywood on Feb. 9 night saw "Parasite" become the first-ever non-English-language film to scoop best picture, the movie industry's biggest prize.
