Secret Santa
RedditGifts is a program that offers gift exchanges throughout the year. The fan-made RedditGifts site was created in 2009 for a Secret Santa exchange among Reddit users, which has since become the world's largest and set a Guinness World record. In 2009, 4,500 redditors participated. For the 2010 holiday season, 92 countries were involved in the secret Santa program. There were 17,543 participants, and $662,907.60 was collectively spent on gift purchases and shipping costs. In 2014, about 200,000 users from 188 countries participated. Several celebrities have participated in the program, including Bill Gates, Alyssa Milano, and Snoop Dogg. Eventually, the secret Santa program expanded to various other occasions through RedditGifts, which Reddit acquired in 2011.
