When the United Nations teamed up with Droga5 to promote World Humanitarian Day on August 19, its goal was to reach hundreds of millions of people with its message,"This World Humanitarian Day I'm doing something good, somewhere, for someone else. Join me! #WHD2012 #IWASHERE." By its own calculations, it blew past that, reaching 1.13 billion people.

"At first, a billion may have seemed too ambitious, but 'good' is an uncanny motivation," said David Droga, founder and creative chairman, Droga5.

Turns out watching a Beyonce video is also motivation. "I Was Here," a song from her 2011 album "4," at the United Nations, served as the inspiration and name for the campaign, which encourages people to make their mark in the world by doing something to help another person. That video takes the No. 1 spot on the chart this week with 3.6 million views.
