A celebrity is a widely-recognized or notable person who commands a high degree of public and media attention. The word stems from the Latin verb "celebrare" but one may not become a celebrity unless public and mass media interest is piqued. There are degrees of celebrity status which vary based on an individual's region or field of notoriety. While someone might be a celebrity to some people, to others he may be completely unknown. A global celebrity on the other hand is someone who is known by most people or is a mainstream celebrity. Such celebrities are also known as either a household name or superstar. For example, photos Virgin Director Richard Branson was notable as a CEO, but he did not become a global celebrity until he attempted to circumnavigate the globe in a hot air balloon and generate publicity for himself. Another high profile categorisation of celebrity status is the A-list, based on the marketability of celebrities. Generally speaking, a celebrity is someone who seeks media attention and most frequently have extroverted personalities. The desire to be notable is implied by some to be a part of western culture and more specifically the American Dream as a measure of success. Celebrities that shy away from the public eye or keep a very separate private life are called a reluctant celebrity. A notable example is Kurt Cobain. On the other end of the spectrum, those that seek out publicity for themselves are often called a media tart whereas those that use their private life as a vehicle for enhanced celebrity status, sometimes desperately, are referred to as a media whore. Examples of this are fake or planned relationships, reality television appearances, celebrity nudity and in extreme cases, scandal or celebrity sex tape.
