Challenge has contestants living together in an overseas residence, and has been around for over 30 seasons. The format of each season changes, however the main premise of the series involves a daily challenge, nomination process and elimination round. U8TV: The Lofters combined the "special living environment" format with the "professional activity" format noted earlier; in addition to living together in a loft, each member of the show's cast was hired to host a television program for a Canadian cable channel. The Simple Life, Tommy Lee Goes to College and The Surreal Life are all shows in which celebrities are put into an unnatural environment. Court shows Originally, court shows were all dramatized and staged programs, with actors playing the litigants, witnesses and lawyers. The cases were either reenactments of real-life cases or cases that were fictionalized altogether. Among examples of staged courtroom dramas are Famous Jury Trials, Your Witness, and the first two eras of Divorce Court. The People's Court revolutionized the genre by introducing the arbitration-based "reality" format in 1981, later adopted by the vast majority of court shows. The genre experienced a lull in programming after The People's Court was canceled in 1993, but then soared after the emergence of Judge Judy in 1996. This led to a slew of other reality court shows, such as Judge Mathis, Judge Joe Brown, Judge Alex, Judge Mills Lane and Judge Hatchett. Though the litigants are legitimate, the "judges" in such shows are actually arbitrators, as these pseudo-judges are not actually presiding in a court of law. Typically, however, they are retired judges or at least individuals who have had some legal experience. Courtroom programs are typically daytime television shows that air on weekdays. Investments The globally syndicated format Dragons' Den shows a group of wealthy investors choosing whether or not to invest in a series of pitched startup companies and entrepreneurial ventures. The series Restaurant Startup similarly involves investors, but involves more of a game show element in which restaurant owners compete to prove their worth. The British series Show Me the Monet offers a twist in which artworks' artistic value, rather than their financial value, is appraised by a panel of judges, who determine whether each one will be featured at an exhibition. Outdoor survival Another subgenre places people in wild and challenging natural settings. This includes such shows as Survivorman, Man vs. Wild, Marooned with Ed Stafford,
