It's interesting that according to this article:
'Elementary' and 'Vegas' picked up for full seasons by CBSElementary has been averaging 14.3 million viewers, making it the second most successful new show this season in viewership (the first is
Vegas with 14.9 million), and it's the second most successful in the 18-49 demo with a 3.5 average rating (the first is
Revolution). Both those figures are higher than what we've been seeing is the Fast Overnight ratings figures, so apparently the show is doing even better than we thought once the complete ratings figures are calibrated.
