Apple faced challenges from IBM in the 1980s when IBM introduced the personal computer. Apple's Lisa computer failed due to being overpriced. Later, Jobs was ousted from the company due to conflicts over business strategy. When Jobs returned to Apple in the late 1990s, he restructured the company by reducing R&D spending, streamlining products, cutting distributors, and opening Apple stores to sell directly to customers. Jobs also grabbed opportunities in digital music players by designing the iPod, helping revive Apple's business.
