The third installment from executive producers Tom Hanks, Gary Goetzman and Mark Herzog, following in the footsteps of critically-acclaimed series "The Sixties" and "The Seventies," tackles 10 years shaped by exceptionalism and excess. Like its predecessors, "The Eighties" intersperses rare archival newsreel footage, interviews, and comments by historians, journalists, politicians, celebrities and others, painting a perspective-rich picture of a vibrant decade. Episodes examine the age of Reagan, the AIDS crisis, the end of the Cold War, Wall Street corruption, the evolving TV and music scene, and everything in between.

AMC has proven its considerable skill in producing historical Western content ("Broken Trail," "Hell on Wheels"). The network dips into the same well again with the limited event series "The American West," a docudrama that shows how, in the aftermath of the Civil War, the United States transforms into the "land of opportunity," a violent world dominated by cowboys, Indians, outlaws and law men. Across eight episodes, little-known stories are told of Western legends such as Jesse James, Billy the Kid, Wyatt Earp, Crazy Horse and Sitting Bull. The series also features exclusive interviews with notable names from classic Western films, including James Caan, Tom Selleck, Kiefer Sutherland, Ed Harris and more.

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.

After scoring a hit with a series set in the 1960s, AMC travels much further back in time for "TURN: Washington's Spies," a Revolutionary War-era drama based on the same-named Alexander Rose novel. The series goes beyond the battlefront to a conflict involving everyday men and women, taking place in a cryptic world of double agents, covert operations and code-breaking. It revolves around Abe Woodhull, a young farmer torn between loyalty to his Tory background and respect for those who fight for the Patriot cause. Living on British-occupied Long Island, Abe joins a group of his childhood friends to form what becomes known as the Culper Ring, a spy network charged with sniffing out British military strategy. Under the direction of Gen. Washington, Abe and his fellow agents help turn the war to the Continentals' favor, and their daring efforts ultimately serve as the foundation for modern espionage.

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.
