Lombardo’s time at HBO saw the introduction of acclaimed shows such as Boardwalk Empire, Girls, True Detective and, perhaps most successfully, Game of Thrones.
HBO programming president Michael Lombardo is to step down after a 33-year tenure with the premium network.
Other properties to have been inducted onto the channel with Lombardo in charge include True Blood, The Leftovers, and Veep.
With the end of Game of Thrones reportedly two seasons away, pressure will soon be on the channel to find a replacement as globally successful.
