Tuesday nightaveraged 3.76 million viewers and a 1.9/5 A18-49 at 10pm Tuesday, almost edging out the broadcast competition on ABC (The Forgotten - 2.0/5 with adults 18-49). That's up in viewers from last week's 3.49 million, and flat with adults 18-49.
So far, the show is outperforming, and by a fairly wide margin, the 2009 performance of FX's Damages and Rescue Me.
One thing we hear a lot about with some of the other cable networks is the # of additional viewers during encore broadcasts. Last week (9/22) in addition to the 3.49 million at 10pm, another 1.53 million watched the 11:02 encore, and another 975,000 watched a Sunday night at 11pm airing. A Friday at 11pm airing averaged 841,000 and Tuesday 1am airing another 739,000. By the HBO math, that's almost 7.6 million for the week, so FX is getting pretty good mileage out of the show.
