The rise of alternative rock in the USA. From its early underground days where bands like Black Flag drew inspiration from the DIY ethos of punk. We explore why the bands that emerged from the underground offered an alternative both to the established music industry and the prevailing politics. Bands like R.E.M., The Pixies and Husker Du, REM breaking into the mainstream charts with 'Losing My Religion', Seattle 'grunge' scene, culminating in the success of Nirvana's 'Nevermind'

The turmoil of 1968 helps Nixon win the presidency. Troop strength in Vietnam peaks and the draft accelerates. Karl Marlantes endures bitter jungle fighting on Hill 484, and draftee Arthur Wiknik gets a grim introduction to combat on 'Hamburger Hill'.

We offer the complete second series of “Ancient Apocalypse” in a single video. In this series, journalist Graham Hancock travels to the Americas to search for evidence supporting his hypothesis: that an advanced civilization was lost to history during the cataclysms that marked the apocalyptic end of the last Ice Age, between 12,800 and 11,600 years ago. Each episode investigates new discoveries being made in the American hemisphere, which until recently has been largely under-explored by archaeologists interested in humanity’s origins. Graham reveals new findings and speculates about how those findings might suggest the existence of a globe-traveling advanced civilization that left traces of itself in ancient cultures.
In episode one, evidence from New Mexico’s White Sands desert confirms the presence of people in the Americas long before it was possible to migrate across the Bering Straits that formed a land bridge during the lowered sea-levels of the Ice Age. The series takes us to multiple locations in the US, Mexico, Brazil, Peru and Easter Island to investigate when people first arrived in the “New World” and how they made the journey. The findings give Graham reason to question the accepted timeline of human history. During his journey, Graham interviews highly regarded archaeologists and historians as well as indigenous elders, who share their unique knowledge of the sites and their oral histories. Hollywood actor, Keanu Reeves, also joins Graham across the series, discussing, among other things, his insights into storytelling as an act of preserving culture. Experts in the series include American archaeologist Dr. Chris Davis, Brazilian palaeontologist Dr. Alceu Ranzi, and archaeo-botanist Dr. Sonia Cardinali of Rapa Nui, Easter Island, among others.

It's this moment where now both sides realize that no quarter will be asked, and no quarter will be given. Surrender is no longer even an option. You're in this to the end. You either die or you triumph, and there is no other alternative. Amid a spiral of brutality and low morale, Mehmed makes Giustiniani an enticing offer. The grand vizier urges Mehmed to seek a truce with his rival.

Zachary Quinto embarks on a journey to understand how artificial intelligence may already be a threat to humanity. He visits Facebook headquarters where he learns about a failed AI experiment where two chat boxes created a language that only they could understand. Zach also gets a firsthand look at the world's latest technology, including life-like dolls programmed with advanced AI, robots that learn and communicate telepathically, highly intelligent drones of war, and Uber self-driving cars.

Hours before Mehmed II launches his final assault, an ominous sight shakes both sides. Rumors of a 40-ship fleet's imminent arrival have swirled for weeks, but it's exact whereabouts remained unknown. Ottoman cannons reduced the city walls to rubble, and Venetian reinforcements arrived too late. The conquest of Constantinople ushers in a new era for the Ottoman Empire, being a dominant force in world politics for 300 years. Mehmed II, in many senses, changed the nature of world history.
