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.
