HBO Programming Chief Exiting

Michael Lombardo

HBO Programming President Michael Lombardo is leaving the company after more than three decades, the latest executive shakeup at the pioneering cable television network.

The LA Times reports the decision to resign was made by Lombardo, said a person familiar with the matter who was not authorized to comment. His final day is not known.

A replacement has not been named. Lombardo is expected to segue to a production deal with HBO.

During his tenure, Lombardo has overseen the launches of the popular series "True Blood," "Boardwalk Empire," "Game of Thrones," and "Veep." The latter two won for both drama and comedy series at last year's Emmys.

But his departure comes as HBO has faced some programming struggles in the past year or so.

Its  blockbuster series “Game of Thrones” continues to be a mega hit. But as the fantasy epic winds down, the network’s search for a strong slate of dramas has faced some challenges.

HBO's expensive rock drama “Vinyl,” executive produced by Martin Scorsese and Mick Jagger, fared poorly. Other big-budget projects in development also have faced troubles.  The TV adaptation of Michael Crichton's futuristic "Westworld" halted production in December and still has an undetermined air date.

The TV industry has changed dramatically during Lombardo's tenure. HBO remains a top destination for high caliber projects, but faces more competition than ever. Rivals such as Netflix, Amazon, Showtime, AMC and FX have grabbed a larger share of business, attracting talent with high budgets and creative freedom.
