When:
Lookups spiked on February 29, 2012.
Why:
"North Korea Agrees to Nuclear Moratorium" was a widely reported news story.
Moratorium means "a suspension of an activity" or "a time when a particular activity is not allowed" and comes from the Latin word that means "delay."
In exchange for food aid from the United States, North Korea agreed to a moratorium on nuclear weapons tests, uranium enrichment, and long-range missile launches - a breakthrough in negotiations with the isolated dictatorship.
