FX is still partying on “Sons of Anarchy’s” finale ratings. The drama delivered 9.26 million viewers for its Dec. 9 finale, according to Nielsen’s live-plus-3 ratings that track DVR viewing within three days of the premiere airing.

With that L3 rating the two-hour seg amounts to the most-watched installment of the series’ 92-episode run, and its highest-rated in all three key demos: adults 18-34 (2.89 million), adults 18-49 (6 million) and adults 25-54 (6.29 million).

FX has determined that “Sons of Anarchy’s” seventh swan-song season ranks as the most-watched season of any series in the cabler’s 20-year history. “Sons” averaged 7.54 million total viewers and 5 million in adults 18-49, which marks a high concentration of younger viewers even for a cable drama.

“Sons” beat its own record as the previous FX record-holder for most-watched season, its sixth.

“It’s a rare and remarkable accomplishment for a television show to generate its – and our channel’s – highest ratings in its final season,” said John Landgraf, CEO of FX Networks and FX Prods. “We thank (creator) Kurt Sutter and his team for an epic ride.”
