Apple has acquired about 100 companies over the last six years, the company’s chief executive Tim Cook has revealed.

Apple’s ten largest purchases put together would still be worth far less than any of those deals.

Not big news, but if you follow the headline link and scroll, you can scan through a list of some of those acquisitions/aquihires.
