Its fairly common for a company to dominate an industry and then disappear. It's more more rare for a company to dominate multiple industries for years at once while continuing to innovative in many others. For Steve Jobs, Apple cofounder and former CEO, the goal of Apple wasnt simply to create great products, but to create a lasting company that will influence the world for generations.
Looking at Apple shortly after Jobs death, its safe to say that he may have been right with his long-term predictions. With large cash reserves, one of the best upper management teams in the industry, and a slew of mega-successful products.
