Quarter Hour breakdown
As frequently happens new viewers sampled the show in the second hour (at 10PM when audiences transition from one show to another) which lead to the 5th quarter hour reaching a strong 1.41, but the audience dropped off thereafter ending with close to the audience the program reached in the 1st quarter hour.
For the 24 week period from Jan 5 - June 19, 2009 TNA iMPACT averaged a 1.208 rating reaching an average of 1,171,760 HHs in Spike TV's "universe". (97 million HH) (HH = Households)
For the ame 24 week period ECW on Sci-Fi averaged a 1.227 rating reaching and average of 1,141,110 HH in Sci Fi's universe (93 million HHs)
So ECW is still slightly ahead in rating average but by only a .019 difference, but trails iMPACT by an average of 30,650 HHs due to the difference in audience reach of the two cable networks.
