The popularity of Ozzy Osbourne has seen sales of his merchandise hit the $50m (£27.2m) mark, a record for a heavy metal artist.
Ozzy's career has been rejuvenated by reality TV
Sales of T-shirts, accessories and action figures have rocketed since TV show The Osbournes hit screens.
Merchandising sold at concerts including Ozzfest raked in $35m (£19m), according to licensing company Signature Networks.
Ozzy vintage clothing is even available in US fashion store Bloomingdales.
"I think the Ozzy for President and the Passion of Ozzy shirts we just released will be some of the best-selling and most popular among his fans," said wife and manager Sharon Osbourne.
"Of course, I love Ozzy so much I sleep with one of his shirts on every night."
Signatures Network, who hold the worldwide merchandising and marketing rights to 125 music artists including U2 and Madonna, said an Osbournes slot machine would be one of the next products on the market.
Ozzy recently returned to performing after suffering serious injuries in a quad bike accident in December 2003, lining up alongside other metal acts at Ozzfest.
Meanwhile, the Osbourne family, including siblings Jack and Kelly, have returned for a third series of MTV show The Osbournes, ensuring the marketing rollercoaster continues apace.
