A celebrity is a widely-recognized or famous person who commands a high degree of public and media attention. The word stems from the Latin verb "celebrere" but they may not become a celebrity unless public and mass media interest is piqued. For example Virgin Director Richard Branson was famous as a CEO, but he did not become a global celebrity until he attempted to circumnavigate the globe in a hot air balloon. Another example is Al Gore, whose environmental crusade has elevated him to celebrity status. On the other hand, mass entertainment personalities such as soap opera actors or music stars are likely to become celebrities even if the person deliberately avoids media attention.
A famous definition of celebrity comes from the cultural theorist Daniel Boorstin. In his book,The Image: A Guide to Pseudo-Events in America, he cynically describes a celebrity as “a person who is known for his well-knownness
Some professional activities, by the nature of being high-paid, highly exposed, and difficult to get into, are likely to confer celebrity status. For example, movie stars and television actors with lead roles on prominently scheduled shows are likely to become celebrities. High-ranking politicians, national television reporters, daytime television show hosts, supermodels[3], successful athletes and chart-topping musicians are also likely to become celebrities. A few humanitarian leaders such as Mother Teresa have even achieved fame because of their charitable work. Some people are internet celebrities and are found in videos online.
While some film and theatre directors, producers, fashion designers, artists, authors, trial lawyers and journalists have achieved celebrity status, in general they are less famous than actors of equal professional importance to the business.
Individuals with their own television show (or sections of television shows) often become a celebrity, even when their profession would not normally lead to celebrity status: this can include doctors, chefs, gardeners, and conservationists on shows like Trading Spaces and The Crocodile Hunter. However fame based on one program may often prove short-lived after a program is discontinued.
