It's nearly impossible to ignore the influence Apple has had in the consumer markets for phones, tablets and personal music players. Even though they were never the first at inventing something, the execution of their products is where they do amazingly well. They build massive hype over their products but also keep them super secret. They're making so much money that they're worth more than some countries in terms of cash available. It's amazing to think in 1997 they were weeks away from going bankrupt, now they're the most valuable company in the world.
