Bartlett has been at Discovery for five years and will exit the US-listed channel operator later this year.
Broadcast broke the news and Discovery confirmed Bartlett’s imminent departure.
The Discovery exec joined the company in 2010, soon after exiting his London-based role as boss of ITV Studios.
He was upped from executive VP to president, Discovery Studios, last year as Marc Graboff joined the company. Bartlett, who will exit in September, reports to Graboff.
His responsibilities at Discovery include overseeing Betty and Raw and he is also Discovery’s primary liaison for All3Media and chairman of its board.
His exit will follow that of Eileen O’Neill, who having been upped to global group president of Discovery Studios, also left the role after a short tenure, albeit longer than Bartlett’s. She was also an All3Media board member.
Discovery had no other comment aside from confirming Bartlett’s departure.
