The Persuasion Machine

Jamie Bartlett reveals how Silicon Valley's mission to connect the world is disrupting democracy, helping plunge us into an age of political turbulence. Many of the Tech Gods were dismayed when Donald Trump - who holds a very different worldview - won the American presidency, but did they actually help him to win? With the help of a key insider from the Trump campaign's digital operation, Jamie unravels for the first time the role played by social media and Facebook's vital role in getting Trump into the White House. But how did Facebook become such a powerful player? Jamie learns how Facebook's vast power to persuade was first built for advertisers, combining data about our internet use and psychological insights into how we think. A leading psychologist then shows Jamie how Facebook's hoard of data about us can be used to predict our personalities and other psychological traits. He interrogates the head of the big data analytics firm that targeted millions of voters on Facebook for Trump - he tells Jamie this revolution is unstoppable. But is this great persuasion machine now out of control? Exploring the emotional mechanisms that supercharge the spread of fake news on social media, Jamie reveals how Silicon Valley's persuasion machine is now being exploited by political forces of all kinds, in ways no one - including the Tech Gods who created it - may be able to stop.

The Disruptors

Jamie Bartlett uncovers the dark reality behind Silicon Valley's glittering promise to build a better world. The tech gods believe progress is powered by technology tearing up the world as it is - a process they call disruption. He visits Uber's lavish offices in San Francisco and hears how the company believes it is improving our cities. But in Hyderabad in India, Jamie sees for himself the human consequences of Uber's utopian vision - drivers driven to suicide over falling earnings. Riding shotgun in a truck as it drives itself for more than a hundred miles on a highway, Jamie asks what the next wave of Silicon Valley's global disruption - the automation of millions of jobs - will mean for all of us. In search of answers, he gets a warning from an artificial intelligence pioneer who is replacing doctors with software - an economic shock is coming, faster than any of us have realized. Jamie's journey ends in the remote island hideout of a former Facebook executive who has armed himself with a gun because he fears this new industrial revolution could lead to social breakdown and the collapse of capitalism.

Lakes and Rivers

Just as Africa constantly throws-up mountains which intercept moisture-laden clouds from the oceans, so the changing landscape also creates grooves and basins which channel and gather the precious moisture that falls on the high ground.

Jungle

Plants amazingly dominate this green world by employing poisons, recruiting defensive armies, feeding off the dead and using animals for pollination and seed dispersal. For predators this world presents exceptional challenges, not only in finding prey in such a tangled place, but in how to deal with the toxins that so many animals and plants are laced with.

Coasts

Africa's coasts were formed by the break-up of Gondwanaland 100 million years ago. They define the familiar shape of this special continent, and touch on a variety of environments including deserts, mountains, forests, wetlands and savannahs. Wild Africa takes us back in time to witness the birth of Africa and also carries us on a spectacular journey around the edge of the continent.

Deserts

As a whole, Africa is a dry continent with deserts dominating the landscape. Wild Africa explores how these deserts were created, and the amazing ways in which animals and plants have evolved to cope with the meagre and unpredictable rainfall, intense solar radiation, shortages of food and lack of shelter. By traveling through the African deserts, Wild Africa reveals that given enough time, a diverse variety of animals and plants can make a living in even the harshest conditions.

Jazz Legends in Their Own Words

A journey into the BBC archives unearthing glorious performances and candid interviews from the golden age of jazz. Featuring some of the greatest names in American music, including the godfather of New Orleans jazz Louis Armstrong, the King of Swing Count Basie, Duke Ellington, Oscar Peterson, Dizzy Gillespie and Ella Fitzgerald. Broadcasted as part of the Old Masters, Rising Stars: Jazz On BBC Four season, this film unlocks the BBC archives to explore the words and music of some of the greatest names in jazz. The BBC soon moved on from Lord Reith's proclamation, made in the 1930s, that jazz was "a filthy product of modernity", and invited some of the legends from the golden age of American jazz to perform and talk on British television. This film is a series of revealing portraits, from Louis Armstrong, jazz's first great soloist and global ambassador, to Duke Ellington, the ever-suave bandleader and composer who brought a new sophistication and ambition to the music. Count Basie is sheer swing, Dizzy Gillespie provoked a musical revolution with bebop, and Ella Fitzgerald is just incomparable. Through long-forgotten archive and specially shot interviews, Jazz Legends In Their Own Words tells the story of an art form that has been called "America's gift to the world".

Hooked on Food

In recent years, eating has become a health hazard. We love our potato chips, candy, and fast food…however bad they are for our health. And we still continue to consume these products in ever greater quantities. After the war on tobacco, a new battle is underway: the fight for healthier food. So, why do we consume so much processed food and why are we so hooked on it? How exactly does the relentless agribusiness keep us coming back for more? How does it mold our tastes, influence our cravings and feed our addictions? The few independent researchers who dare raise concerns about processed food are often ignored. Opposite them, the giant multinationals who fund the majority of research into nutrition are highly organized, and present at every level of decision-making. They are even involved in government campaigns on nutrition and health. Remi, our French-American reporter, will investigate current eating habits in Europe and America, and meet those involved in this new global food war. We will hear from scientists tracking sugar addiction, the businessmen playing on our weaknesses, legal experts preparing to challenge the might of the industry, and simple lovers of good food. A compelling documentary that reveals the latest ways the agribusiness is trying to tempt us, and the ways we as consumers can try to resist.
