A celebrity is a person who commands a high degree of attention from the public and the media.  It can be a sports figure, a movie star, a musician, or a politician.   Al Gore, was Vice President of the United States, but he became a celebrity when he took on the cause of Global Warming, and made a movie that people the world over, viewed with great shock about the state of the planet.   This is called “mass-celebrity”, when people around the world are familiar with and have an interest in you. A famous definition of celebrity was once written in a book by Daniel Boorstin called “The Image:  A Guide to Pseudo-Events in America.  In this book, he wrote that a celebrity is “a person who is known for his well-known-ness”.
