On Wednesday, NBC benefited from its decision to run new programming against a slate of repeats.

Last night, it was CBS' turn, as America's most-watched network lived up to that distinction by airing record-breaking episodes of The Big Bang Theory and Person of Interest.

Sheldon and company, for example, drew 19 million people to their playing of real-life Jenga, setting a series high for total viewers and tying it with a 6.0 in the young adult demographic.

Person of Interest, meanwhile, enjoyed similar success: a high in its total audience (16.1 mil) and the matching of its all-time best 18-49-year old rating (3.4).

Elsewhere on CBS:

• Elementary (11.4 million/2.5) enjoyed its best figures since the pilot.
• Two and a Half Men rose to season highs in the same categories: (15.4 million and 4.6, respectively).
