Ozzy Osbourne was an architect of heavy metal music, but that’s not the only medium in which he blazed a trail.

The rocker, who died Tuesday at the age of 76, also helped shape reality television. An argument might even be made, for better or for worse, that Osbourne and his family gave rise to the Kardashians.

The idea of celebrities doing reality shows was far from common in 2002, when MTV first launched “The Osbournes.”

Ozzy Osbourne’s music career was no longer at its height as he and his wife, Sharon, opened the doors of their home to share to share their private life with their then-teen children, Jack and Kelly, as well as their beloved pets.

Audiences fell in love with the family members, as funny as they were fascinating. It was quite a different version of Osbourne, who was known as the “Prince of Darkness” for his stage performances, including the now infamous story of him biting the head off a bat.
