I've seen some chatter commenting on Burn Notice's numbers so far since its return last week. Sure, the viewer numbers aren't quite as good as they are during the summer, but it's live and same day DVR viewing base is pretty strong and its 18-49 numbers are holding up very well. Even during the summer it hovered around a 2.0 live+SD rating with adults 18-49 and sometimes a little bit lower. Don't get hung up on total viewer numbers, they really don't matter much here.
Both episodes since its January return have performed nearly identically. Last week's mid-season premiere averaged a 1.9 adults 18-49 rating and 5.351 million viewers and last night averaged and a 1.9 adults 18-49 rating 5.304 million viewers.
At least with these numbers, there's absolutely no reason to fret over the show's fate at all, not to mention, it actually has already been renewed for a 4th season that will begin this summer. A 1.9 adults 18-49 rating makes you a cable ratings stud.
Last week it was the number one scripted drama with adults 18-49 on cable (though it missed out being USA's most-watched show with adults 18-49 by 1,000 viewers to WWE Monday Night RAW, though it did edge out RAW with adults 25-54).
This week it will again be USA's top scripted show. White Collar had a 1.3 adults 18-49 rating and Psych had a 1.5. I don't think you need to worry about any of those shows either. My guess is that USA is happy with the way those shows are performing while airing during the regular TV season (compared to summer viewing that has more reruns going on the broadcast nets). And even if you want to worry anyway, there's no need to worry yet. White Collar has already been renewed for a second season.
