I haven’t caught the first few episodes of the third season yet, but they must be solid because HBO has decided to bring “Big Love” back for a fourth season.

Skein drew 1.5 million viewers in its initial run Sunday at 9 p.m., growing its audience 29% over Jan. 18’s season-three premiere despite competition from the Super Bowl on NBC.

The show is averaging nearly 5 million viewers per episode when DVR viewing, encore runs and video-on-demand deliveries are factored in — a performance on par with that of HBO’s frosh hit “True Blood.”

Season-four production is set to start later this year with episodes slated to run on the pay cabler in 2010.

“Big Love” is a great show and it’s nice to see that HBO is standing behind it.
