Osbourne gained high visibility in 2002 after appearing in his family's reality television show The Osbournes, which aired on MTV and won an Emmy Award in 2002.
 In the show, Osbourne was mostly shown as a rebellious teenager who liked to party and to fight with sister Kelly Osbourne.
In a song by Tenacious D advertising The Osbournes, Jack Black sings the line "and he's got a big 'fro on his head" to describe Osbourne's curly hair that grew longer until he eventually shaved it off in the third season of the show.
In 2002, Osbourne briefly appeared in Austin Powers: Goldmember along with the rest of his family, and subsequently starred in a Super Bowl XXXVI advertisement for Pepsi Twist with sister Kelly.
From 2002 to 2003, Osbourne appeared in Season 6 of Dawson's Creek, playing Audrey's childhood friend.
He also made cameos in The X Factor (as a "Goth rapper" who sings "Ice Ice Baby"), the fifth season of That '70s Show as a dmv customer and as a dining room guest in the eighth season of Hell's Kitchen.
Post-rehab, Osbourne went on in 2003 to star in his own show on Channel 4, Union Jack.
In 2004 he played a small role in New York Minute, a film starring the Olsen twins, in which he plays a music promoter named Justin.

In 2005, Osbourne started to show more of an interest in fitness through co-hosting the ITV2 show, Celebrity Wrestling: Bring It On!.
In February that year, he appeared in Extreme Celebrity Detox in which he took part in t'ai chi and climbing exercises, which possibly inspired him to appear in his own programme, Jack Osbourne: Adrenaline Junkie produced by the same production company (Ginger Productions) as Extreme Celebrity Detox.
Osbourne lost (50Lb) 23 kg in Thailand at a Muay Thai martial arts camp in Pattaya in order to be fit enough to climb El Capitan (which he achieved) whilst filming the first series of Jack Osbourne: Adrenaline Junkie.
It aired on ITV2 in the UK, the Travel Channel in the United States, The LifeStyle Channel in Australia, GOtv in South Africa and on MuchMusic in Canada.
Adrenaline Junkie focuses on Osbourne's training for sports like rock climbing, mountaineering and a jungle trek in Belize from the Chiquibul Chamber through dense jungle ending at Caracol ruins (guided by the UK extreme conservation organisation Trekforce).
He showcased the effects of his weight loss with the two semi-naked photo shoots for Cosmopolitan magazine in 2005 to raise awareness of testicular cancer.
The first, taken in June 2005, shows him sitting on a motorbike; the second appeared in the December 2005 issue.
After the first series of Adrenaline Junkie he began filling in for Stephen Mulhern on CITV's Saturday morning kids' show Holly & Stephen's Saturday Showdown (the show has now ended).
Osbourne took part in Sport Relief and faced former singer in the band S Club 7, Bradley McIntosh, in a boxing match of three one-minute rounds to raise money for the charity.
Osbourne won by a unanimous decision.

He once claimed to be considering a career in law enforcement and was on reality television show Armed & Famous.
The show was pulled from CBS in January 2007, and Osbourne was sued by a woman from Muncie, Indiana, whose house was accidentally raided during filming.
Osbourne also filmed a programme in Namibia for the BBC's Saving Planet Earth series.
He also took part in the Mongol Rally with News Corporation director Andrew Knight's daughter, Amaryllis Knight.
Osbourne and his family reunited with a reality TV show on Fox that debuted 31 March 2009 but was cancelled after the first episode.

Osbourne made and produced a documentary about his father that was originally to be titled to Wreckage of My Past: The Ozzy Osbourne Story, but was changed to God Bless Ozzy Osbourne.
This film premiered in April 2011 at the Tribeca Film Festival and was released on DVD in November 2011.
In early August 2010, Osbourne directed his first music video, for his dad's song "Life Won't Wait" from the album Scream.
The video debuted on 23 August.
Osbourne worked for Fuse News from February 2013 to early 2014.
