1 - Tractor Revolution

In the 1870s, harvesting crops is grueling, back-breaking work. Farmers must walk miles behind horse drawn plows to get food on American tables. But a group of dreamers--all of them rivals--has a vision that will change farming forever and create one of the world's most iconic machines: the tractor. Their quest to corner the market--worth 75 billion today--produces some of the greatest innovations and most iconic brands of all time: Caterpillar, John Deere, and Ford.

In 1910, airplanes are a novelty, fragile wooden concoctions that float in the air--and crash. But that doesn't stop two young dreamers with a passion for this newfangled machine from imagining a very different future: one in which planes carry millions of passengers across the country, even across the seas. To realize that vision and create a lucrative new market, William Boeing and Donald Douglas take on automobile titan Henry Ford, infamous Dutch aviation giant Anthony Fokker--and each other.

Goliath battle, fighting to dominate a market valued at more than 7 billion dollars today, the rivals will push their machines to the limit and tap into the lure of the open road.

5 - Telephone Wars

In the 1870s communicating with distant family requires sending a letter, and waiting days or weeks for a reply. The telegraph is faster, but too expensive for most people.

Alexander Graham Bell and Elisha Gray will stop at nothing to lay claim to the new technology and dominate the market.
