Not just NBC as a network history, in the history of the three old networks, CBS, ABC, NBC and then the later Fox.
Rival networks were predicting premiere 18-49 rating a little below the 2.0 that fellow midseason NBC drama Deception recently opened to, with a 1.8 rating considered a reasonable target. But Do No Harm came in at a 0.9, the lowest in-season premiere rating for a series on the Big 4 broadcast networks. Ever.
I only saw ads for it on NBC, which no one normally watches, and no matter how many ads you show, it won't matter if they make the show look like crap.
Let the NBC bashing continue!
