A little over 20 million people watched President Obama's second inauguration on television, Nielsen reported Wednesday afternoon.
The ratings agency counted up the viewers across 18 different networks. It said that 20.552 million people watched coverage airing from 10 AM to 4:30 PM on Monday. (CNN was the top-rated cable news network, and NBC the top-rated broadcast network.)
The numbers were a steep drop from Obama's first inauguration, which drew 37 million viewers, and was the second-lowest rating for an inauguration since 1969, as the New York Times' Bill Carter noted.
