Some dates on the calendar are just dates. November 15 is not one of them. Three times, on three different November 15ths, America changed direction — and the three events could hardly be more different. In 1864, a Union general marched out of Atlanta and changed how wars are fought. In 1867, a telegrapher unveiled a machine that changed how money moves. And in 2001, Microsoft launched a black box that changed how the world plays. All three happened on November 15.

1864: Sherman Marches Out Of Atlanta

On November 15, 1864, Union General William Tecumseh Sherman began his March to the Sea. With about 60,000 soldiers, he left the captured city of Atlanta and set off on a 285-mile campaign through Georgia toward Savannah, living off the land and destroying railroads, factories and supplies as he went. Before leaving, his engineers blew up the city’s railroad depot — the wreckage photographed that same day, November 15, 1864, is the image at the top of this story. Sherman reached Savannah on December 21 and offered the city to President Abraham Lincoln as a “Christmas gift.”

The march was a new kind of war. Armies had always fought other armies; Sherman fought the economy that fed the other army, and the idea — total war against an enemy’s capacity to keep fighting — has shaped every war since. The photograph of the ruined depot, taken by the army’s photographers on the very day the march began, is one of the earliest war photographs ever made, and it still shows what the campaign meant: not a battlefield, but a city’s infrastructure, deliberately unmade.

1867: The First Stock Ticker

Exactly three years later, on November 15, 1867, the first stock ticker was unveiled in New York City. The inventor was Edward Calahan, a telegrapher who rebuilt a telegraph machine to print stock prices on a continuous strip of paper tape. The machine got its name from the sound its type wheel made as it printed — a ticking clatter — and it did something no one had done before: it put up-to-the-minute prices in front of investors around the country, instead of making them wait for a messenger to run from the exchange.

Before the ticker, information from the New York Stock Exchange travelled by mail or messenger. After it, a broker in another city could watch prices move almost as they happened. The Gold & Stock Telegraph Company rented the machines to brokerage houses for $6 a week, and by the 1880s about a thousand tickers were installed in New York offices. Thomas Edison improved the design in 1871 with his Universal Stock Printer — the invention that made his name — and the paper tape the ticker printed gave the world a phrase that outlived the machine itself: the ticker-tape parade.

2001: The Xbox Arrives

On November 15, 2001 — 25 years ago today — Microsoft launched the Xbox game console in North America. The company that had built its empire on Windows and Office was betting it could break into a business dominated by Sony and Nintendo, and it did it with a heavy black box, a built-in hard drive, and a launch title that became a legend: Halo: Combat Evolved. The Xbox sold out quickly, and Microsoft has been in the console business ever since, through the Xbox 360, the Xbox One, and today’s Series X and S.

The date has collected other history too. On November 15, 1777, after 16 months of debate, the Continental Congress approved the Articles of Confederation, America’s first constitution. On November 15, 1889, Brazil was declared a republic. On November 15, 1920, the first assembly of the League of Nations met in Geneva. And on November 15, 1971, Intel released the 4004, the world’s first commercial single-chip microprocessor — the chip that started the computer age. But the three that define the date are the ones that each remade a world: war, money, and play, all on the same square of the calendar.

War, money and play — three worlds remade on the same square of the calendar, 137 years apart.

THE STORY SO FAR

November 15, 1777 — After 16 months of debate, the Continental Congress approves the Articles of Confederation.

November 15, 1864 — General William Tecumseh Sherman begins his March to the Sea from Atlanta with about 60,000 soldiers. The city’s railroad depot is destroyed the same day.

November 15, 1867 — Edward Calahan unveils the first stock ticker in New York City, printing live stock prices on paper tape.

November 15, 1889 — Brazil is declared a republic as Emperor Pedro II is deposed.

November 15, 1920 — The first assembly of the League of Nations is held in Geneva, Switzerland.

November 15, 1971 — Intel releases the 4004, the world’s first commercial single-chip microprocessor.

November 15, 2001 — Microsoft launches the Xbox game console in North America, with Halo: Combat Evolved as its flagship launch title.

WHAT HAPPENS NEXT

December 21, 1864 — Sherman reaches Savannah and offers the city to President Lincoln as a “Christmas gift,” ending the March to the Sea. The campaign becomes the model for total war.

The ticker’s legacy — Edison’s improved ticker follows in 1871, and the paper tape it printed gives the world the ticker-tape parade. The last mechanical ticker debuts in 1960.

The Xbox at 25 — a quarter-century after launch, Microsoft’s console business continues with the Xbox Series X and S, and Halo remains its flagship series.
