Reality TV has focused the camera on pawn shop owners, housewives, fashion designers, chefs and those aspiring to enter the world of food.
With shows like "Top Chef," "Big Brother" and “Project Runway,” the format of television has changed — American audiences have become the talent and the 'stars.'
Along with 'real people' many of today's celebrities have joined this burgeoning entertainment format, which now comprises nearly half of TV’s prime-time hours.
Celebrities like Shania Twain and Ozzy Osbourne have chronicled their everyday lives on their own reality shows, “Why Not? With Shania Twain” and “The Osbournes.”
Mark Burnett, the producer who introduced competitive reality television to the U.S. with "Survivor" and "The Apprentice," has forever changed the television landscape.
Real estate mogul Donald Trump, the boss who dispatches contestants with the well-known phrase “You’re fired,” became the face of “The Apprentice” as well as its celebrity edition.
George Hamilton, Cloris Leachman, Susan Lucci and others have put on their dancing shoes to compete on “Dancing With the Stars.” The show teams up a professional dancer with a celebrity, has them master a dance routine and then perform it before a live audience.
And then there’s “American Idol.” Introduced to American audiences by British entrepreneur Simon Fuller, the blockbuster talent show made household names of Ryan Seacrest, the show’s host, and one of its judges, Paula Abdul, singer, choreographer and former Los Angeles Lakers’ cheerleader.
Here's a look at some of the celebrities who have had their own show or have appeared on a reality program.
