Rage Against the Machine guitarist Tom Morello, who served as musical director for Osbourne’s final show, shared a photo with the late singer on Instagram, writing, “Good bless you Ozzy.” Metallica’s X account also shared an image with Osbourne with a heartbroken emoji.

After Ozzy shaped the sound of heavy metal, he became a reality TV star. Here's a look back at the iconic moments from his MTV show, "The Osbournes."

Ozzy Osbourne, the former lead singer of British band Black Sabbath, was about to rock. The mood was festively macabre. Posters for the “Diary of a Madman Tour” showed Osbourne in his “Prince of Darkness” alter ego — complete with devil horns — and warned attendees that eating before the concert was “not recommended.

Ozzy Osbourne 's family was an important part of his life. The heavy metal icon, who died at 76 on July 22, spent many of his later years soaking up quality time with his children. The Black Sabbath lead singer got a second act as one of America's most beloved dads, sharing another side of himself on The Osbournes, which premiered on MTV in 2002.

Hours after Osbourne's death, Idol spoke with The Hollywood Reporter about Osbourne's musical legacy, and the path he carved for the musicians who came after him.

Ozzy Osbourne was fifty-six and living in Beverly Hills when he spoke to Esquire for its What I’ve Learned interview series. This story appeared in the January 2005 edition of Esquire US. Osbourne died on 22 July at the age of seventy-six.

During its relatively short run from 2002 to 2005, “The Osbournes” became a runaway hit and made stars of his wife Sharon and kids Jack and Kelly. But more than that, it made a star of the domesticated version of Ozzy Osbourne, and in the process changed reality TV.
