On Tuesday, December 3rd, the second annual #GivingTuesday took place. Encouraging people all over the world to take place in what started as a national day of giving, the campaign celebrates and contributes to the success of charitable activities that support millions of nonprofit organizations.

This year online donations by Blackbaud rose 90% to $19.2-million, with the average gift hovering around $142. Network for Good, which also processes online donations, said it handled $1.8-million in gifts on Tuesday.

In 2012 there were more than 2,000 recognized #GivingTuesday partners in the U.S. During that 24-hour period, Blackbaud processed more than $10 million in donations while DonorPerfect recorded a 46% increase in online donations on that day over the Tuesday after Thanksgiving in 2011.

The #Unselfie, in which participants take a picture of themselves holding a piece of paper with the name of a charity they support-- either through volunteer work or donations-- and post it to their social media networks, helped contribute to the trend and was a leading keyword in the days leading up to Tuesday.
