Comic and political provocateur W. Kamau Bell hosts this CNN original documentary series in which he travels to the far corners of America to explore race-based subcultures. Using humor to soften his experiences, Bell willingly subjects himself to awkward situations -- like attending a cross-burning, hate-mongering Ku Klux Klan session -- to demonstrate "the many diverse and colorful definitions of America," CNN says. Bell also visits a gated retirement community, experiences inner-city policing, spends time with spring break revelers, speaks to prison inmates, and travels to the Last Frontier.

Narrated and co-executive produced by Oscar winner Kevin Spacey, "Race for the White House" captures the high-stakes drama, dirty politics and Machiavellian schemes employed during history's most dramatic presidential elections. Using archival footage, interviews and stylized dramatizations, each hourlong episode tells the story of one presidential campaign, "a four-year, no-holds-barred battle to become the most powerful person in the world, culminating in a single night of heart pounding tension," says CNN. Among the races covered: Abraham Lincoln/Stephen Douglas, John F. Kennedy/Richard Nixon, and George H.W. Bush/Michael Dukakis.

Executive-produced by Tom Hanks, Gary Goetzman and Mark Herzog, CNN's eight-part documentary picks up where the network's critically acclaimed and highly-rated series "The Sixties" ended. Episodes examine the people, events and cultural touchstones that defined the '70s, delving into everything from the impact of the Vietnam War to the unprecedented scandal of Watergate. Also covered are the Iran Hostage Crisis, the sexual revolution, the Munich Olympics massacre, and the kidnapping of Patty Hearst. The documentary combines archival newsreel footage, personal movies, interviews, and comments by historians, journalists, politicians, celebrities and others, bringing new perspectives about a consequential decade.

Former House Intelligence Committee Chairman Mike Rogers hosts this CNN original series, an eight-part look at complex true stories of America's covert operations. The newly declassified missions are recounted firsthand by agents from all 16 U.S. intelligence bureaus, providing viewers with unprecedented access to a secret world of espionage. The missions span time periods from Cold War-era Moscow to modern-day Iran, from the streets of 1980s Cuba to Beijing of today. Among the stories covered are the military's hunts for Iraq dictator Saddam Hussein and al-Qaida leader Abu Musab al-Zarqawi.

With the Vietnam War, the British Invasion, Woodstock, the Civil Rights Movement, and JFK's assassination, the 1960s represent, perhaps, the most consequential decade in U.S. history. It was a period of monumental social and political change, altering virtually every aspect of American life for future generations. "The Sixties," a 10-episode documentary executive-produced by Tom Hanks, Gary Goetzman and Mark Herzog, explores the people, events and discoveries that defined how citizens came to think about their government, their place in the world, and themselves. It combines archival newsreel footage, personal movies, interviews, and comments by historians, journalists, politicians, celebrities and others, bringing new perspectives about a landmark decade.

Anthony Bourdain had no reservations about a move to CNN. Shortly after concluding an eight-season stint at the helm of his popular Travel Channel series, the equally popular Emmy-winning host came to the news network searching for "Parts Unknown." In the hourlong weekend series -- similar in premise to Travel's "No Reservations" -- Bourdain explores the world to, he says, "eat and drink with people without fear and prejudice ... they open up to you in ways that somebody visiting who is driven by a story may not get." Enticed by the opportunity to experience cultures rarely visited by American TV, such as in the Congo, Libya and Myanmar, the chef and best-selling author also takes viewers to Colombia, Peru, Morocco and, closer to home, Koreatown in Los Angeles.

From local news and sports reporter to correspondent on ABC's "Good Morning America" and "Nightline," Bill Weir has taken a varied path in his journalism career. Another turn came when he joined CNN in 2013 to develop original programming, giving birth to "The Wonder List." In hourlong episodes, Weir travels with cinematographer Philip Bloom to five continents to tell stories of extraordinary people, places, cultures and creatures, which are at a crossroads. In a world of rapid change, how is the intrusion of modernization, climate change and tourism affecting the Galapagos, the Greek island Ikaria, the French Alps, the Dead Sea, the Florida Everglades, India, Venice, and Vanuatu, an island chain in the South Pacific? In 2050, will there still be tigers in the wild? Will the Taj Mahal still be standing? Will there still be Alps to climb and ski? "We set out to create time capsules of places we all agree are precious," Weir says.

Award-winning journalist and author Lisa Ling reports on unconventional lifestyles in the U.S. The former co-host of "The View" introduces viewers to subcultures and communities that are extraordinary and sometimes dangerous, and her interpersonal skills prompt interviewees to discuss matters they don't share with close friends or even family. "I have always believed that the more we know about each other, the more evolved we become," Ling says about the intent of the hourlong documentaries.

Victims' rights activist John Walsh returns to weekly TV as host of a documentary-style investigation series. Walsh details stories of ongoing cases involving fugitives, with the intent of expanding searches outside the United States. Interviews with victims, loved ones and law enforcement accompany new leads in each hourlong episode, giving the public information to facilitate the capture of suspects. Walsh, a spokesman for the National Center for Missing & Exploited Children, hosted the series "America's Most Wanted" for 25 years, helping apprehend more than 1,200 criminals.
