TNA iMPACT on Spike TV averaged a 1.219 rating for the period from Jan 5-May 29 (21 weeks)
ECW on Sci-Fi averaged a 1.242 rating for the same period
So based on ratings one might think ECW is leading TNA iMPACT in season to date average.
The rating is the % of US Households watching the show on the cable network.
However, Spike TV is available in approximately 97 million HH while Sci Fi is available in only 93 million HH (Households), but ratings are based on each cable network’s household audience reach, which is different from broadcast which is based on all available US households.
For example the CBS Network is available in apoproximately 113 million households.
So TNA’s 1.219 rating = 1,182,430 HH on Spike TV
And ECW’s 1.242 rating = 1,155,060 HH on Sci-Fi
Winner is TNA iMPACT
