Our philanthropic efforts reflect the diverse interests of our key businesses and focus on several distinct areas: arts education; arts and culture; health and human services; civic and community outreach; education; the environment; and volunteerism. Each operating company has its own philanthropic priorities and unique resources, from product donations to recordings and screenings that benefit a multitude of causes.

Sony Pictures Entertainment is a major supporter of arts education and community involvement, with emphasis in Culver City, California, its world headquarters. Collectively, we have also been quick to provide assistance when large-scale disasters have struck. We've helped victims of major hurricanes, earthquakes, wildfires and the attack on the World Trade Center.
