What Is the History of .mobi?
The .mobi domain was proposed in 2004 by dotMobi, a consortium of leading mobile technology companies including Nokia, Samsung, Ericsson, Vodafone, T-Mobile, and Google. After approval by ICANN in 2005 and delegation in October 2005, it became operational in 2006. Afilias acquired dotMobi in 2010 and took over registry operations. In 2018, Afilias transferred management of .mobi to Identity Digital Limited, which now operates the domain under ICANN’s sponsored TLD framework. While the original intent was to create a mobile-exclusive zone, today it is used more broadly for mobile-responsive sites and branding.
