"NIGHTLINE"'S DAN HARRIS NAMED HOST FOR SEASON TWO OF ABC'S "500 QUESTIONS," THE INNOVATIVE EVENT GAME SHOW FROM MARK BURNETT AND MIKE DARNELL

Dan Harris has been named host for season two of ABC's innovative event game show "500 Questions," from Mark Burnett and Mike Darnell. Produced by MGM Television in association with Warner Horizon Television, the series will return in 2016.

Harris is currently co-anchor of "Nightline" and the weekend edition of "Good Morning America" on ABC News. He also regularly files reports for "World News Tonight with David Muir," "20/20," "Good Morning America," ABC News Digital and ABC News Radio. Previously, he anchored "World News Sunday."

In 2014 Harris published the book, "10% Happier: How I Tamed the Voice in My Head, Reduced Stress Without Losing My Edge and Found Self-Help That Actually Works." It went to #1 on the New York Times Bestsellers List and then became an app, designed to teach meditation to skeptics. Harris first joined ABC News in March 2000 and has covered many of the biggest stories in recent years. He reported on the mass shootings in Newtown, Connecticut, Aurora, Colorado and Tucson, Arizona, and natural disasters from Haiti to Myanmar to New Orleans. He has also covered combat in Afghanistan, Israel, Gaza and the West Bank, and has made six visits to Iraq. He has traveled around the globe for ABC News, embedding with an isolated Amazonian Indian tribe, questioning drug lords in the lawless slums of Rio, and confronting the head of Philip Morris International over the sale of cigarettes to Indonesian minors. Harris has made it a priority to shine a light on the world's most vulnerable populations, producing stories about child slaves in Haiti, youths accused of witchcraft in the Congo and predatory pedophiles who travel from the U.S. to Cambodia. He has also covered endangered animals from such diverse datelines as Namibia, Madagascar, Papua New Guinea and Nepal.

"500 Questions" challenges the smartest people in the country to achieve the seemingly impossible task of answering 500 of the most difficult general knowledge questions ever devised. There's only one simple rule: never get three wrong in a row - or you're gone. No saves, no helps, no multiple choice, "500 Questions" keeps you on the edge of your seat to see if any of these geniuses can do it. It is the ultimate test, where intellect, strategy and stamina are all equally essential in order to win.

Mark Burnett and Phil Parsons are the executive producers. Ed Egan is the co-executive producer. The show was created by Mike Darnell and Mark Burnett.
