It’s official: “Boardwalk Empire’s” upcoming season will be its last.

HBO made the announcement during the first day of the Television Critics Association’s Winter Press Tour in Pasadena, Calif., as executives confirmed this would be the Prohibition-era mob drama’s fifth and final season.

The series, starring Steve Buscemi as the force behind sketchy dealings in Atlantic City, will return in the fall. “After much discussion with my creative team and HBO, we’ve decided to wrap up the series after such a great run and look forward to bringing it to a powerful and exciting conclusion,” series creator Terence Winter said in a statement.

Meanwhile, the network also said “Veep” and “Game of Thrones” will both debut Sunday, April 6, for their third and fourth seasons respectively.

Also premiering that night will be “Silicon Valley,” a new comedy from Mike Judge (“Office Space,” “Beavis and Butthead”). The show looks at the tech-world and how “the people most qualified to succeed are the least capable of handling success.”
