Friday night shows do not usually have huge numbers under normal circumstances. Even though this is the February sweeps period, most networks only have reruns to show due to the writer's strike. Sooooo.... that means last Friday's ratings were especially low across the board for all the television networks.
Ratings for Moonlight's Fever episode (#1x04) on Friday, February 1st, 2008 ~
Fast Nationals : 5.91 million viewers (2nd), 18 to 49 demo share 1.5/ 4 (3rd)
In my opinion, those are not bad numbers for a repeat episode. Comparing Moonlight to the other shows that night, none had high ratings. For example ~
In Moonlight's time slot (8:00 PM CST/9:00 PM Eastern), on Fox, House won with 7.83 million viewers.... NBC's Friday Night Lights got 5.64 million.... ABC's Desperate Housewives had a very low 3.64 million.
7:00 PM CST/8:00 PM Eastern
Ghost Whisperer (CBS) 7.31 million viewers.
Bones (Fox) 5.59 million viewers.
Grey's Anatomy (ABC) 4.13 million viewers.
9:00 PM CST/10:00 PM Eastern
Numb3rs (CBS) 6.89 million viewers.
Las Vegas (NBC) 6.86 million viewers.
20/20 (ABC) 6.75 million viewers.
