About 37.75 million viewers watched President Obama’s 2012 State of the Union address, which featured a farewell appearance by Rep. Gabrielle Giffords and aired live across 14 broadcast and cable networks. That was down 12% from last year’s speech, which was watched by 42.79 million people and down 21% from Obama’s first State of the Union in 2010 (48 million). Like his approval ratings, Obama’s TV ratings have been sliding since the post-inauguration high of 52.37 million viewers who tuned in for his address to the joint session of Congress in February 2009. Among the cable news networks, Fox News dominated the field with 3.8 million viewers vs. 2.8 million for MSNBC and 2.7 million for CNN.
