The Ad Council is a non-profit agency which since 1952, has been the leading producer of television public service announcements, often "sponsored" by specific non-profit groups and government agencies. Ad Council spots typically address such issues as public safety, personal health, and wider issues such as adoption. Their best known creations include Smokey Bear and McGruff, the dog who "takes a bite out of crime." Various advertising agencies over the years have donated their services in creating the campaign.
