Fast National ratings for Tuesday, October 19, 2010.
 
With "Glee" airing a repeat on Tuesday, "NCIS" wasn't just the night's most-watched program, it was also the night's top show in the all-important demographic. The powerful procedural helped CBS sweep the primetime hours in the key measures.
 
Meanwhile, the absence of "Glee" and "Raising Hope" sent a new "Running Wild" plummeting to series lows, putting the show on a rather serious cancellation watch.
