Here's the ratings scoop, courtesy of an article from MediaWeek entitled, wait for it, Sons of Anarchy Hauls Ass for FX. Sons of Anarchy did great in the ratings. There was 4.13 million total viewers.
Per Nielsen live-plus-same-day ratings data, the Sons premiere now stands as the most-watched cable scripted series telecast of 2010 among the coveted TV demo, drawing 2.81 million viewers 18-49.
The funniest thing is that I forgot about the premier, but saw a commercial for it during Covert Affairs on USA. The ad was literally "SOA is on FX right now!" So I did tune in for a bit of the premier.
