HBO’s “Boardwalk Empire” wrapped its five-season run Sunday to an audience of about 2.3 million viewers — up 7% from last year’s finale but down a bit from its season premiere in September (2.4 million).

With additional replays, the series finale totaled 3 million viewers for the night, the largest Sunday night audience for the series this season.  Season to date, “Boardwalk Empire” is averaging a gross audience of 6.6 million viewers per episode.

Its largest regular-timeslot audience over its run came with the show’s September 2010 series premiere, which averaged 4.81 million viewers.

“Boardwalk Empire” is one of three HBO dramas ending their runs in 2014. “True Blood” exited in August after seven seasons, and “The Newsroom,” which will take over the “Boardwalk” timeslot on Nov. 9, is airing a third and final season consisting of six episodes.
