Season averages: 3.10 in the demo with 13.41 million.

This was a positive start for the new series, particularly in viewership, but the demo could have been stronger — especially considering the fairly lackluster competition (Scandal on ABC and Rock Center with Brian Williams on NBC).

Compared to the season premiere of The Mentalist a year ago, CBS was up by 10% in the demo (vs a 2.8 rating) and down by 1% in viewers (vs 13.56 million).

Note: These ratings are collected by the Nielsen company and are the final national numbers. These are different from the fast affiliate numbers which are just estimates of the actual ratings and are reported on by most other outlets. The final nationals are typically released within 24 hours of the programming or, in the case of weekends and holidays, a couple days later.
