How do you create a message so powerful, riveting, and inspiring that it reaches one billion people worldwide? For starters, you can enlist the help of an influential superstar, like Beyoncé. Each year, on August 19, the United Nations commemorates the 2003 bombing of the UN headquarters in Baghdad, Iraq with World Humanitarian Day (WHD). This time around, they got help from Mrs. Knowles-Carter, whose Diane Warren-penned ballad, “I Was Here,” provided the soundtrack to the massive, social media initiative.

The megastar’s “1 day, 1 world, 1 message” campaign debuted earlier this month, encouraging people to use social media to pledge one act of kindness, great or small, for another human being on WHD2012. By August 19, over 1 billion people committed to the effort via Facebook and Twitter, topping the original goal by more than 33 million pledges worldwide. Beyoncé even commemorated her participation by shooting visuals for her 4 single during the August 10 session of the United Nations General Assembly in New York (and she stunned in a sequined, white Marc Bouwer gown, no less).
