DESCRIPTION: (from NBC's press release, March 2017) The Emmy Award-nominated "American Ninja Warrior" returns for its sixth full season on NBC. Matt Iseman is back as host, along with Akbar Gbajabiamila and co-host Kristine Leahy. The action-packed series follows competitors as they tackle a series of challenging obstacle courses in both city qualifying and city finals rounds across the country. Those that successfully complete the finals course in their designated region move on to the national finals round in Las Vegas, where they face a stunning four-stage course modeled after the famed Mt. Midoriyama course in Japan. The winner will take home a grand prize of $1 million. This season the show will make stops in Los Angeles, Calif.; San Antonio, Texas; Daytona Beach, Fla.; Kansas City, Mo.; Cleveland, Ohio; and Denver, Colo., before heading to Las Vegas for the national finals. Last year "American Ninja Warrior" delivered its most-watched season ever, averaging 7.2 million viewers, and was a top-10 summer series among primetime programs on the Big 4 networks in every key ratings measure.
