In January 2003, Public Interest Registry became officially responsible for operating .ORG and maintaining the authoritative database of all .ORG domain names. The transition of .ORG from the previous operator to Public Interest Registry was the largest transfer in Internet history. More than 2.6 million domains were transferred in about a day, without affecting any .ORG registrant or website.
Today, there are over 10.3 million .ORG domain names registered all around the world. From small, local groups to huge, global foundations, a diverse range of noncommercial organisations use .ORG to advance their missions. Even many for-profit businesses use .ORG to gain support for their charitable activities.
