Apple has just confirmed plans to purchase Beats Electronics for $3 billion. The acquisition ranks as the largest that Apple has ever made and will see the company take ownership of an enormously successful and profitable line of consumer headphones as well as a burgeoning subscription music service. Beats co-founders Jimmy Iovine and Dr. Dre will also join Apple as part of the acquisition, which it will pay for with $2.6 billion in cash and $400 million in stock.
