Twentieth Century Fox’s exec VP of digital marketing Ira Rubenstein is ankling his post after just over a year on the job.

Exec joined Fox in May of last year.

Move brought Rubenstein full circle, as he began his career at Fox as manager of film research and new media. Between his stints at the studio, Rubenstein held posts at Marvel and Sony.

During his short time with Fox, Rubenstein headed the studio’s digital marketing activities, reporting to chief marketing officer Oren Aviv and chief creative officer Tony Sella.

Exec’s exit comes on the heels of news that Fox co-chairman Tom Rothman will leave his post at the end of the year. But one studio insider denies that Rubenstein’s departure is part of a larger shakeup.

Rothman’s departure raised questions about the new duties of his senior execs, most notably production prexy Emma Watts and others on the production teams.

Reasons behind Rubenstein’s departure were not immediately clear.

Rubenstein launched Marvel’s digital subscription service, as well as digital video channels on Netflix, YouTube, iTunes, Hulu, Xbox Live and Sony’s PlayStation Network. Before that, he shepherded Sony Pictures Digital Entertainment’s websites, mobile expansion and the launch of its online VOD service Movielink as the company’s exec VP of Sony Pictures Digital Entertainment.
