Same again for last night. Lowest numbers yet. With Mentalist and Grey's, not much chance of that changing tonight. NBC claims they can still make money even if he his continually last. So there is the new broadcast business model...profit from mediocrity.
Part of the plan is that Leno will pick up audience during the 40-50% of the year when scripted programming is in re-runs.
Essentially for the cost of one night of programming they get an entire week, and hope to win audience during off weeks.
For all the complaints, one has to remember that NBC is essentially "free TV". You can get an antenna in most parts of the country and a DVR that can skip commercials and have the "free content". One should really be complaining about all the cable channels that charge you every month, ones that you are forced to buy filled with commercials and very little original programming.
