Exec joined Fox in May of last year.
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.
