Some 26.1 million people watched President Barack Obama's prime-time State of the Union address, as the big four broadcast networks each devoted at least 90 minutes to their coverage.

The CW's decision to counterprogram with first-run episodes paid off, meanwhile. One Tree Hill got 1.9 million viewers at 8/7c, and Hellcats had nearly 2.2 million people watching it. In its new night and time, Hellcats had its biggest audience since Sept. 29. And the combination of the two shows lifted the CW to its most-watched Tuesday night of the season, according to Nielsen.
