Osbourne's biggest financial success of the 1990s was a venture named Ozzfest, created and managed by his wife/manager Sharon and assisted by his son Jack. The first Ozzfest was held in Phoenix, Arizona, on 25 October 1996 and in Devore, California, on 26 October. Ozzfest was an instant hit with metal fans, helping many up-and-coming groups who were featured there to broad exposure and commercial success. Some acts shared the bill with a reformed Black Sabbath during the 1997 Ozzfest tour, beginning in West Palm Beach, Florida. Osbourne reunited with the original members of Sabbath in 1997 and has performed periodically with them since.
