Delicious (formerly
del.icio.us) is a
social bookmarking web service for storing, sharing, and discovering
web bookmarks. The site was founded by
Joshua Schachter in 2003 and acquired by
Yahoo in 2005. By the end of 2008, the service claimed more than 5.3 million users and 180 million unique bookmarked
URLs. Yahoo sold Delicious to
AVOS Systems in April 2011, and the site relaunched in a "back to
beta" state on September 27 that year. In May 2014, AVOS sold the site to Science Inc.
