"Thanks to Terry Winter, Martin Scorsese, Tim Van Patten, Howard Korder and their stellar team,Boardwalk Empire remains in a class by itself," HBO boss Michael Lombardo said in a statement. "I look forward to another electrifying season of this impeccably crafted series."
The fourth season premiere which aired on Sept. 8 was watched by 2.4 million viewers, a weak beginning compared to last year's 2.9 million set of eyeballs.
On the bright side, the series gained recognition at the Emmy's a week ago when Bobby Canavale bagged the award for Outstanding Supporting Actor In a Drama.
'Boardwalk Empire' airs every Sunday at 9/8c on HBO.
