NBC TV chief says fall season ‘worse than I hoped for’

NBC entertainment chief Robert Greenblatt admitted on Friday that the struggling TV network got off to a ‘really bad’ start last fall, after low ratings and cancellations of several high-profile new shows. But Greenblatt said he had high hopes for upcoming new shows including musical drama series ‘Smash’ and the return of surprise 2011 summer talent show ‘The Voice.’
