Apple co-founder Steve Jobs, who revolutionized the recorded music industry with the introduction of iTunes and the iPod, died Wednesday (Oct. 5) at age 56 of complications from pancreatic cancer. Launching Apple in 1976 with high school friend Stephen Wozniak in a California garage, he built an empire in the computer and consumer electronics industry and played a major role in expanding the popularity of music players and cell phones with the introduction of the iPod, iPhone and iPad. While major record labels grappled with illegal downloads and searched for viable ways to offer paid downloads to consumers, Apple introduced iTunes in January 2001 and quickly dominated the world of digital music. Jobs underwent surgery in 2004 and received a liver transplant in 2009. He stepped down as Apple's CEO in August.
