A senior Apple director who has recently led marketing efforts for the company’s Vision Pro headset has retired following a career that spanned over 36 years, reports Bloomberg.

Frank Casanova was Apple’s first head of marketing for augmented reality and later Vision Pro until his retirement, which he confirmed last week through his LinkedIn profile. Casanova’s early career also saw him lead efforts within Apple to expand the iPhone’s availability through carriers. Casanova attended Vision Pro’s retail launch in February at an Apple Store located at The Grove, a shopping mall in Los Angeles. Casanova was joined by Senior Vice President of Services Eddy Cue during the headset’s Los Angeles launch.

Vision Pro has now been available in the United States for over two months, but a recent report from Ming-Chi Kuo believes that local demand for the headset is waning. Kuo now estimates that Apple will only get to sell less than half a million units of its headset worldwide, down from an earlier estimate of nearly 800,000 units.

Apple still plans to launch Vision Pro across international markets this year, which could commence between now and the start of WWDC 2024 on Monday, June 10. Apple is said to unveil visionOS 2 during its developers conference, the first major software release for Vision Pro four months after its market debut.

Casanova’s retirement is the latest in a series of high-profile departures from Apple, one that included its oldest-serving industrial designer who was part of the legendary team led by Jony Ive. Another high-profile executive who left Apple is now said to be working on new hardware for OpenAI, rumored to be an AI-based smart home product, under Ive’s LoveFrom design consultancy firm.
