#GivingTuesday just completed its fourth year, and by most measures it has already become a successful fixture in the charity landscape. Launched as a response to the overt consumerism of Black Friday and Cyber Monday, #GivingTuesday focuses the attention of the world on the true meaning of the holiday season: sharing our capacity to care for and empower one another. According to a preliminary estimate by the Case Foundation, #GivingTuesday raised $45.7 million for nonprofits this year, representing a nearly 240 percent increase from the $13.46 million generated just two years ago when the event first launched.
