Fast National ratings for Tuesday, January 6, 2015.

The new year is off to a good start for CBS as, for the second straight night, the network's various procedurals neared or cleared season highs, led by the most watched "NCIS" since last February.

"NCIS" and "NCIS: Los Angeles" had no trouble thumping ABC's two-hour "Marvel's Agent Carter" in all measures. While ABC will happily note that "Agent Carter" outdrew "Agents of S.H.I.E.L.D." throughout, the 1940s-set drama suffered a dwindling audience at each half-hour.

Elsewhere, a good premiere for "MasterChef Junior" pushed "New Girl" to a solid performance, though "The Mindy Project" took a big fall from its lead-in.
