Apple has bought more than 20 companies since November, but we know about only 6 of them
Among those 20-plus acquisitions is Apple's December purchase of Platoon, a startup that works directly with musicians to produce and distribute their work. In March, Apple reportedly acquired an application-programming-interface-development startup called Stamplay.
The company has $225 billion in cash and securities on its balance sheet, according to its most recent earnings, which makes Apple one of the most cash-rich enterprises in tech. It also means Apple has a lot of opportunities and incentive to spend.
