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, 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 have achieved fame online and thus are Internet celebrities.
