Nielsen: 67-Million Viewers For First Presidential Debate

The Nielsen ratings company says an estimated 67.2 million people watched the first debate between President Barack Obama and challenger Mitt Romney, the largest TV audience for a presidential debate since 1992.

Eleven TV networks carried Wednesday night's debate live. Telemundo showed it on tape delay.

Nielsen says you have to go back to the second debate involving Bill Clinton, George Bush and Ross Perot in 1992 for a more popular presidential debate.

Four years ago the vice presidential debate between Joe Biden and Sarah Palin attracted 69.9 million viewers.
