Osbourne was famously singled out during the 1985 U.S. Senate hearings that led to the adoption of "Parental Advisory" labels for explicit content on music releases. He later starred in the reality TV show The Osbournes, introducing him and his immediate family to a new generation of fans. He appeared in the documentary Sunset Strip and the film Little Nicky, the series Ozzy and Jack’s World Detour, and he co-hosted the comedy podcast The Osbournes Podcast.
