With the death of Ozzy Osbourne, former MTV boss Van Toffler remembers the success of "The Osbournes," and how it impacted both MTV and reality TV.

My heartfelt sympathies go out to Sharon, Jack, Kelly, the rest of his family and everybody that's worked hard along the way."

Transformed by 'The Osbournes' from bird-biting Prince of Darkness into one of TV's quintessential bumbling dads, Osbourne helped usher in a wave of image makeovers with unexpectedly lasting ripples.

Ozzy Osbourne, the hellraising frontman of Black Sabbath and reality TV star, has died aged 76. The news was confirmed via the Associated Press on Tuesday, who included a statement from the Osbourne family:

Ozzy Osbourne’s sisters are grieving the loss of their beloved brother. Jean Powell and Gillian Hemming opened up to The Mirror about their sibling, whose real name was John Michael Osbourne, and spoke about the last time they saw and talked to him.

Insiders say Black Sabbath's Back To The Beginning show in his hometown on July 5 made him a much younger man in his last days.

Kelly Osbourne made her first public comments on Thursday, two days after the death of her father, rock legend Ozzy Osbourne. "I feel unhappy I am so sad," Kelly Osbourne wrote in an Instagram story.
