"This was a short message. It includes the U.S. seal to make it clear that it's official, and it also includes a notice that the ads were paid," said Nuland. "As you know, after the video came out, there was concern in lots of bodies politic, including Pakistan, as to whether this represented the views of the U.S. government. So in order to ensure we reached the largest number of Pakistanis -- some 90 million -- it was the judgment that this was the best way to do it."
The messages run about 30 seconds, and are a compilation of speeches and YouTube clips edited together. The production was overseen by the U.S. embassy in Islamabad with input from the State Department in Washington.
The ads show Obama saying, "Since our founding, the United States has been a nation of respect, that respects all faiths. We reject all efforts to denigrate the religious beliefs of others."
Clinton follows with a speech she's made several times since the crisis in the Middle East began unfolding last week.
"Let me state very clearly that the United States has absolutely nothing to do with this video. We absolutely reject its contents. America's commitment to religious tolerance goes back to the very beginning of our nation," she says in the video.
The effectiveness of the announcements is still in question. Nuland said today that it was still too early to evaluate whether the messages are working, given the massive protests.
"I don't think it's going to be realistic to give you kind of a metric report on our efforts in this week or next," said Nuland.
