Yahoo! 360° was a social networking and personal communication portal operated by Yahoo! made available in 2005. It enabled users to create personal web sites, share photos from Yahoo! Photos, maintain blogs and lists, create and share a public profile and see which friends are currently online. 360° also featured a 'friends updates' section, under which each friend's latest update was summarized (e.g. blog posts, updated lists or newly shared photos). This service was never officially launched; Yahoo! prematurely stopped developing this service in 2008.
Yahoo! 360° Plus Vietnam is a similar service that is available in Vietnam. This service was launched in 2008 and is still active.
Yahoo 360° launched as an invitation-only service on March 29, 2005. After the full launch on June 24, 2005, it became available to any Yahoo! user over the age of 18 in the United States, the United Kingdom, France, Germany, Canada, Australia, Japan and Vietnam.
From September 2006 through September 2007, the US-based web traffic visiting 360° dropped by more than half. The service had a more global appeal than some of its counterparts, but its global visits also saw a significant drop during the same time frame.
On October 16, 2007, Yahoo announced that they would no longer provide support for or perform bug fixes on Yahoo! 360° as they intend to abandon it in early 2008 in favor of a "universal profile" that will be similar to their Yahoo! Mash experimental system. They have, however, said, that it will not be replaced with Mash itself.
On May 6, 2008, Yahoo announced that they have several Vietnam-centric initiatives as part of their Southeast Asia business strategies. One of these initiatives were Yahoo! 360° Plus Vietnam, a new Vietnamese blogging application. Subsequently, Yahoo! 360° Plus Vietnam was launched in Vietnam along with other new services for Yahoo! Vietnam such as Yahoo! Music (no longer active since 2009). By the end of January 2010, the number of registered users has increased to 1,500,000.
In May 2009, while the service was still in Beta stage of development, Yahoo! announced that Yahoo! 360° service will be officially closed on July 13, 2009 as Yahoo! developers aimed to "focus their efforts on the new profile on Yahoo". Users were given options to move their Yahoo! 360° information and blog to the new profile before this deadline. Yahoo! 360° Plus Vietnam, however, is still active.
