The Sked: Monday Ratings Advisory December 12

Tonight's ESPN Monday Night Football game (the 2-10 St Louis Rams at the 5-7 Seattle Seahawks) will have a limited impact on the broadcast fast nationals in the morning.  In St Louis, the game will be carried locally by FOX station KTVI instead of the Terra Nova original and House repeat.  The St Louis market is ranked #21 and has 1.094% of the nation's TV audience.  Look for the fast national Terra Nova rating to go down between one and two-tenths of a rating point in the official national ratings.

In Seattle the game is being carried on a non-network station and will run mostly outside of prime time.  So the larger market (ranked #12 with 1.580% of the audience) will not have any effect on the fast nationals.
