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 programme is discontinued. In areas of the world where the relevant programme is not being broadcast, a such person is very likely not to be known.
In order to reserve themselves the possibility to have a private life, some local celebrities prefer to live in a part of the world where they are rather unknown; thus, an entertainer who is well known in the German-speaking world could chose to live his private life in the U.S. and fly into Germany to perform his shows (as Thomas Gottschalk actually does), and on the other hand, a U.S. celebrity could decide to privately live in Europe.
