Apple is Licensee and Investor of Imagination Technologies (PowerVR)
According to a press release from Imagination Technologies Group, Apple is "subscribing for" 8,200,000 new shares of Imagination Technologies Group which means Apple will have an ownership interest of 3.6% in the company. The press release also reveals that Apple is a licensee of Imagination's technology.
This is the first public confirmation that Apple is both a licensee and investor in the company which is responsible for the PowerVR 3D chipset for the iPhone and iPod Touch.
In September, Imagination Technologies announced that they had secured a new "multi-year, multi-use license agreement" with an unnamed company that gave access to both current and future PowerVR graphics and video cores. Apple was speculated to be the licensee at that time.
