What will it take for NBC to finally decide that the time for "Heroes" has come and gone?

This week's ratings might be it. After two weeks of matching a series low, "Heroes" found a way to do even worse as it languishes in its new timeslot, and remains unable to keep audiences tuning in for "Chuck."

"Heroes" earned a a 2.4 rating/4 share, according to Fast National ratings from The Nielsen Co. That was more than 17 percent off its premiere in the 9 p.m. slot, itself a now previous all-time low for the series. It also becomes NBC's lowest-rated program of the season overall, beating out the previous low set by "The Jay Leno Show" on Nov. 9 that picked up a 2.6/5.

"Heroes" didn't even come close to challenging its competition, which included the high-rated comedy block of "Two and a Half Men" and "Big Bang Theory" on CBS, "24" on Fox and "The Bachelor" on ABC. It only beat the series premiere of "Life Unexpected" on The CW, but did it only by 41 percent. We say "only" because the other show closest to "Heroes" in the timeslot, "The Bachelor," beat "Life Unexpected" by 312 percent.

"Chuck" came down a little bit from its triad premiere last week. It clocked in a 3.9/6, down a little more than 9 percent from its previous week. That's mostly on par with how the show did last season when it earned a 4.0/6 in average overnights.

That means "Heroes" lost more than 38 percent of its lead-in audience from "Chuck." That's also the same percentage "Heroes" is now off of its already low-rated premiere, and is now more than 22 percent off its season average. This is the second week "Heroes" is at 9 p.m., averaging a 2.7/4 in the timeslot, 23 percent off its 8 p.m. average of 3.5/5.

Fast Nationals usually provide a snapshot of what Americans are watching by pulling numbers from the top urban markets that includes both live viewing and same-day timeshifted viewing. A rating point generally represents more than 1.1 million households while the share indicates the percentage of televisions turned on that was tuned to the specific program. These numbers typically shift when final ratings are issued.
