"The Walking Dead" has reached new lows.

The AMC zombie drama still remains one of cable TV's highest rated shows. But the Season 9's last episode was its lowest-rated finale ever.

Sunday night's finale — which kicked off a snowmageddon arc — was watched by 5.02 million viewers and received a 1.9 rating among adults 18-49 on its first airing.

The previous low for a finale was Season 1's cap, which brough tin little under 6 million and a 3.0 in the demo.

Season 9 as a whole averaged 4.95 million viewers and a 1.9 in the demo in live+same day ratings. That's down 37 percent in viewers and 44 percent in the demo versus Season 8.

The only good news is that the finale rose from last week's series low ratings (4.15 million viewers, 1.5 in adults 18-49).

Despite the inexorable drop in viewership, "The Walking Dead" remains the No. 1 series on cable (excluding sports and news) this season by a wide margin. But it will likely have to give up that badge of honor when HBO's "Game of Thrones" premieres on April 14.
