Apple has picked a replacement to help run its iAd platform, following last year's departure of Andy Miller.
Teresi has had roles at a number of technology companies, most recently Adobe Systems, where he was vice president and general manager of the company's media solutions group. Prior to that he held roles at Quantcast, Yahoo, and PriceWaterhouseCoopers.
An Apple spokesman declined to comment on Teresi's hiring.
As part of his new position, Teresi will report directly to Apple Senior Vice President Eddy Cue, who wasamong several other parts of the company in September.
Teresi fills the spot left by Andy Miller, who. Miller had joined the company as a vice president of mobile advertising following Apple's acquisition of Quattro Wireless, of which he was co-founder and CEO.
Apple introduced its iAds platform in 2010 to take Google and other advertising companies head on. Apple positioned it not only as a new source of revenue for itself, but also to help developers make money from their apps, even if those apps were free. Its big feature at launch was letting people view and interact with advertisements without being jettisoned from the application, something that's the norm in Web advertising but can be jarring to users on mobile devices.
The platform began on applications designed for the iPhone and iPod Touch, and was later expanded to work on the larger-screened iPad. Apple has also created an entire application to demonstrate its capabilities, as well as some of the existing campaigns on the service.
