On 4 October 1957, Soviet scientists launched Sputnik 1 - a beach ball-sized, radio-transmitting aluminium alloy sphere - into orbit. The satellite caused a sensation. Amid Cold War tensions, the Soviet Union’s accomplishment signalled a dramatic technological advantage and American felt it had little choice but to join the Space Race.

What exactly was it going to take for America to beat the Soviets to the moon? Cold War tensions persisted, as rumours circulated that the Soviets were preparing to send an unmanned spacecraft to the moon. Nasa quickly developed the Gemini program, sending astronauts into orbit around the Earth to practice critical manoeuvres for the eventual trip to the moon.

After the immediate celebration of 1968’s successful Apollo 8 mission, underlying questions about the space programme emerged with new intensity as politicized young Americans challenged the nation’s priorities. Nasa pushed brashly forward.

McCarthy chronicles the rise and fall of Joseph McCarthy, the Wisconsin senator whose zealous anti-communist crusade would test the limits of American decency and democracy.

Explore the life of 1970 Nobel Peace Prize winner Norman Borlaug, who tried to solve world hunger. He rescued India from a severe famine and led the "Green Revolution," estimated to have saved one billion lives. But his work later faced criticism.

The latest in our award-winning series of presidential biographies, this film looks at the life and presidency of George W. Bush, from his unorthodox road to the presidency to the terrorist attacks of 9/11 and the myriad of challenges he faced over his two terms, from the war in Iraq to the 2008 financial crisis.

George W. Bush, part two continues through Bush’s second term, as the president confronts the devastating impact of Hurricane Katrina and the most serious financial crisis since the Great Depression.

Part 1 and 2 of a six-part chronicle of the Abraham Lincoln-Mary Todd relationship begins with their childhoods and courtship. He, of course, was born into poverty; she, however, grew up in luxury, the daughter of a Kentucky banker and slave owner. (Several of her brothers would die fighting for the South in the Civil War.) While he was something of a rube when they met, she was the opposite, polished and refined. Yet they shared something in common: a love of politics. The marriage of Abraham and Mary Todd Lincoln proves to be a tempestuous affair accented by her temper, his depression and their political ambitions. Included: his elections to the U.S. House of Representatives and, later, the presidency.

Over one hundred years ago, Americans looked forward to the uncertainty of a new century with a mixture of confidence, optimism and anxiety. Following a range of characters from famous public figures to ordinary citizens, this chronicle of a year in the life of America examines the forces of change that would come to shape the twentieth century.

The Country and the City, 1609-1825: New York, notes narrator David Ogden Stiers, "was a business proposition from the very start," when Henry Hudson, exploring for the Dutch East India Company, sailed into its harbor. Part 1 also focuses on New Yorker Alexander Hamilton, the first Treasury Secretary; and Gov. DeWitt Clinton, who built the Erie Canal. "All America," says Stiers, "now met in New York."

A profile of quintessentially American composer Stephen Foster features interviews with historian Fath Ruffins, biographer Ken Emerson, musicologists Josephine Wright and Dale Cockrell, and modern-day musicians influenced by Foster's work.

Recalling the summer of 1964 in Mississippi, when student volunteers from around the country joined local activists in an effort to register to vote as many African-Americans as possible. (Due to intimidation and arcane tests, less than seven percent of the state's African-Americans were registered.) Activists also set up schools to teach children about African-American history; and created a rival Democratic Party to challenge the all-white delegation to the 1964 Democratic National Convention.

Of all the 19th century pioneer stories, none exerts so powerful a hold on the American imagination as this, during the worst winter ever recorded in the High Sierras. In June, 1846, 87 men, women and children began their legendary 2,000 mile journey from Illinois to California. They packed huge wagons, took food, hired servants. When family leaders made the fateful decision to take an untried short cut to beat the coming winter, only half would come out alive.

"Order and Disorder: 1825-1865" recalls a period of tremendous growth and ferment. Most of the new arrivals were Irish immigrants (100,000 by 1842—and that was before the potato famine), and the subsequent overcrowding led to the construction of Central Park (1857-58). But that didn't quell the ferment, which exploded in 1863 with the racially charged draft riots. "It was the largest incident of civil disorder in U.S. history," notes historian Mike Wallace.

"Sunshine and Shadow: 1865-1898" During the Gilded Age, New York "was home to the greatest concentration of wealth in human history," says narrator David Ogden Stiers. And, he adds, "the greatest concentration of poverty." This episode surveys that dichotomy, from Fifth Avenue mansions to slums documented by Jacob Riis in "How the Other Half Lives." Also recalled: the fall of William H. "Boss" Tweed ("he took a fall for the system," claims Pete Hamill).

"City of Tomorrow (1929-45)" focuses on Mayor Fiorello LaGuardia, who used his close ties to FDR to make the city "a gigantic laboratory of civic reconstruction"; and master builder Robert Moses, who "adapted a 19th century city to 20th century circumstances," says historian Kenneth Jackson. The biggest one: the car. Says narrator David Ogden Stiers: "It challenged all previous assumptions about urban life."

War letters from the American Revolution to the Gulf War are read by 15 actors (including Joan Allen, Edward Norton, Kevin Spacey and Courtney B. Vance). Accompanied by clips, home movies and re-creations, the letters reflect the horror, boredom, anger and, mostly, fear that war engenders. Many readings are followed by notations that the writers had died, but the hour isn't unrelentingly grim. “Pucker up,” one WWII GI writes to his sweetheart on VJ Day. “Here I come.”

Examines the story behind the November 1978 mass murder-suicide in Jonestown, Guyana, where more than 900 people were led to their deaths by cult leader Jim Jones. Included: comments from Jones' son, Jim Jr.; survivor Stanley Clayton; and Hue Fortson, whose wife and child died in the incident.

What drove a company of American soldiers — ordinary young men from around the country — to commit the worst atrocity in American military history? American Experience focuses on the 1968 My Lai massacre, its subsequent cover-up, and the heroic efforts of the soldiers who broke ranks to try to halt the atrocities and then bring them to light.

The Amish practice of shunning those who leave their faith is explored through the experiences of individuals who have left their communities. Also: faithful Amish men and women share the heartbreak they feel when a loved one leaves.

First responders, journalists, shop owners, those inside the pressure-packed control center of Con Edison on West End Avenue, and other New Yorkers tell about what happened when the lights went out on July 13, 1977

Part 3 of 3. In the fall of 1918: a major American offensive that could bring a swift end to the war, a lost U.S. battalion surrounded by German forces, a deadly flu epidemic on the homefront.

"The Power and the People: 1898-1914" recalls the era of mass immigration. "The entire world would arrive on the city's doorstep," says narrator David Ogden Stiers (1.2-million in 1907 alone). "There was a message," says writer Pete Hamill. "Come here, everything is possible." The program also follows the political career of "Happy Warrior" Al Smith; and charts the construction of the subways and the rise of skyscrapers in the clogged city.

John Brown could be seen as a hero or a madman (perhaps both), but either way, there's no doubt he played a role in igniting the Civil War. Actor Joe Morton narrates a chronicle of Brown's life (1800-59), which features archival stills, atmospheric re-creations and the comments of historians. Interviewed: Russell Banks, Bruce Olds, Margaret Washington, Dennis Frye, Edward Renehan, James Horton, James Stewart, Paul Finkelman and Charles Joyner.

The third part recalls 1863, when opposition to the Civil War spread among Northerners: some see the high level of casualties as unacceptable, while others resent fighting to free black slaves. Abraham Lincoln, understandably, becomes anxious. Mary Todd Lincoln, meanwhile, copes by spending money compulsively, and falls into debt as a result. Conclusion. The final 16 months of the Civil War are charted, including the battle at Gettysburg and Abraham Lincoln's battlefield dedication and, just days after the South's surrender at Appomattox, his assassination. Included: Abraham's dedication to bringing the South into the Union; Mary's private wish for revenge.
