Two-time Super Bowl champion and Hall of Fame quarterback Peyton Manning hosts a robust exploration of what makes someone or something the G.O.A.T. -- the "Greatest of All Time" -- across a wide range of disciplines, from toys, inventions, and sports cars to daredevils and titans of industry. Featuring 8 episodes, each one counts down the 10 most iconic people, places, or things through vigorous debate from experts and analysts (including Bob Costas, Neil deGrasse Tyson, Rob Parker, Nicole Lyons, Rutledge Wood, and many more). They weigh in on the skills and historic impact of the list, ultimately deciding who or what deserves the title of "G.O.A.T." by the end of each episode. Only one will be in that top spot -- who or what will it be, and will you agree?
