Maybe for HBO, but a lot of basic cable channels would KILL for 1MM viewers. Heck, Mad Men only gets 2.6MM viewers an ep and that's a huge success. Not to mention the positive economic difference in production costs...
EDIT: I was trying to find it and found references to the show Cinematech although I'm fairly sure I watched a full playthough of Hitman and most of the cutscenes from Far Cry instead of just trailers over the course of 30min.
