a player can achieve it by winning challenges (either as a team in the tribal phase or individually in the merged phase), or, in more recent seasons, through finding a hidden totem. They can also pass on their immunity to someone else and in the latter case, they can keep their immunity secret from other players. On most shows, immunity is quite a bit simpler: it is usually achieved by winning a task, often a relatively minor task during the first half of the episode; the announcement of immunity is made publicly and immunity is usually non-transferable. At some point in the season, immunity ceases to be available, and all contestants are susceptible to elimination. Competition shows that have featured immunity include the Apprentice, Big Brother, Biggest Loser, Top Model, Project Runway, Lego Masters, and Top Chef franchises. Immunity may come with additional power as well, such as in Big Brother where the winning contestant usually has influence over deciding who faces an elimination vote later in the week. In one Apprentice episode, a participant chose to waive his earned immunity and was immediately "fired" by Donald Trump for giving up this powerful asset. Sports Sport-related reality shows can fall within the aforementioned sub-genres, either using it as the basis of competition, or by following sport as a profession: Competition-based programs, featuring groups of athletes completing against each other in challenges and events within a specific sport, such as athletics (American Ninja Warrior, Exatlon), golf (The Big Break), auto racing (Crash Course, Hyperdrive, Pinks), and combat sports (The Contender, The Ultimate Fighter) for example. In the case of combat sports examples, the UFC-produced mixed martial arts competition series The Ultimate Fighter, and the WWE's professional wrestling talent searches Tough Enough, Diva Search, and NXT (before it was reformatted as a standard wrestling show focusing upon up-and-coming talent), a contract with the respective organization is the grand prize. Some series may follow non-sportspeople (usually celebrities, or in some cases athletes known for their participation in a different sport) training and participating in a sporting event, such as The Games, Irish series Celebrity Bainisteoir (where celebrities are tasked to become the managers of mid-level Gaelic football teams), and Dancing on Ice (a figure skating competition series with similarities to Dancing with the Stars). Documentary-style series following specific competitions, teams, or athletes, such as Hard Knocks (NFL), Drive to Survive (Formula One), Knight
