President Obama wasn't as big a draw with his 2013 State of the Union address as he was with his 2012 address. (And in 2012 he wasn't as big a draw as he was in 2011.) According to preliminary ratings, an average of 18.1 million viewers tuned in to the 9:00 p.m. to 10:00 p.m. segment on the four major broadcast networks. That was down 30 percent from the 25.93 million who watched his SOTU address a year earlier. With 6.3 million viewers of the total, CBS delivered the biggest audience, largely due to the fact that the president's speech followed a rerun of the network's hit NCIA: Los Angeles, which recorded 9.1 million viewers during the 8:00 p.m. hour. NBC was close behind with 5.9 million, followed by ABC with 4.6 million and Fox with 2.1 million. Otherwise, for all of the networks, it was a night mostly of reruns that produced tiny ratings. For Example, a rerun of ABC's Modern Family, which usually averages close to 10 million viewers, saw its audience plunge to 3.3 million, a season -- and perhaps a series -- low.
