Apple has become the world's first public company to be worth $1 trillion. Since the iPhone first went on sale in 2007, Apple shares have soared by 1,100% and have jumped almost a third in the past year. Apple traces its origins to the garage of co-founder Steve Jobs in 1976 and was initially best known for its Mac personal computers before its smartphone paved the way for the app economy.
