Guinness World Records, known from its inception in 1955 until 1998 as The Guinness Book of Records and in previous U.S. editions as The Guinness Book of World Records, is a reference book published annually, listing world records, both human achievements and the extremes of the natural world.
In 2005 Guinness designated 9 November as International Guinness World Records Day to encourage breaking of world records. In 2006 an estimated 100,000 people participated in over 10 countries. Guinness reported 2,244 new records in 12 months, which was a 173% increase over the previous year. In February 2008, NBC aired The Top 100 Guinness World Records of All Time and Guinness World Records made the complete list available on their website.
