Picture it: it's 1843.

00:05

The written word has spread around the world in the form of cheap books and daily newspapers. [Old car driving down a black and white street]

00:10

New forms of transportation, like railroads and steamships, have made mail much more efficient. [Train drops off parcels]

00:15

It's becoming almost impossible to avoid nagging letters from annoying relatives.

00:21

Almost.

00:22

But those annoying relatives were about to have some revolutionary new tools at their [Woman opens her postbox and takes out a letter]

disposal...

The ability to speak to someone instantly, whether they were in another room, another

state, or on the other side of the world. [People in the different places]

00:33

Was it magic…?

00:34

Wormholes?

00:35

Telepathy?

00:36

No, no, and not a chance.

00:37

It was actually something cooler than all three of those things. [People getting electrocuted]

00:41

Electricity!

00:42

So the first of these breakthrough electrical technologies was the telegraph.

00:47

This handy dandy long distance communication machine was created in the early 1800s by [Early telegraph machine]

00:51

a guy named Samuel Morse.

00:53

How did it work?

00:55

Y'know…science and stuff.

00:56

Okay, okay…we’ll be more specific. [Magnifying glass highlights post it note with specific written on it]

00:58

The basic idea was that it sent electric pulses through a wire between telegraph stations. [Telegraph wires with electricity pulsing through them]

01:04

So a person on one end would tap out a series of these pulses on their telegraph… [Person tapping on a telegraph machine]

01:10

And then a person on the other end would interpret the message.

01:12

But wait…how did the guy on the other end know what a series of electric pulses meant?

01:17

Who communicates in electric pulses, besides robots and maybe those guys from Daft Punk? [Daft Punk and a robot zap each other with electricity]

01:21

Well, turns out humans do if they know Morse code.

01:24

That’s right…as some have probably figured out already, Samuel Morse was the guy behind [Picture of Samuel Morse holding up the morse code]

01:29

Morse code.

01:30

Thus continuing the time honored tradition of naming stuff after yourself.

01:35

Such humility.

01:36

Morse code took letters and numbers and assigned them a series of dots and dashes. [Samuel Morse using a telegraph machine]

01:40

Short clicks from the telegraph equaled dots, and long clicks equaled dashes.

01:45

Letters that got used all the time, like E, have a simple code…

01:49

While neglected letters, like Q, got a complex one.

01:52

Poor Q…look on the bright side, that'll be good material for your therapist. [The letter Q sat on a therapist's chaise longue]

01:57

The very first telegraphs actually made marks on paper showing the dot and dashes.. [Letters appearing on a piece of paper]

02:02

But it didn’t take long for people to figure out that telegraph operators could hear the

02:06

clicks coming through…

02:07

So newer telegraphs amped up the sound, allowing the operators to write down the message. [Man writing on a piece of paper]

02:13

Morse sent his first telegraph message in 1844.

02:16

It traveled from Washington, D.C. to Baltimore, and it said…"Is your refrigerator running?" [Refrigerator bounces along revealing the quote]

02:23

….Okay, just kidding, it actually said "What hath God wrought?" [The quote is written out on paper]

02:27

Yeah, it may sound a little melodramatic, but there’s no denying that the telegraph

02:32

had major effects on the world. [People hold the arms up to the telegraph machine]

02:34

As telegraph lines spread across the U.S. and the globe, information could be spread much

02:38

more quickly.

02:39

Journalism spread faster….

02:41

Money could now be wired… [Man pulls money out his postbox]

02:43

And wars were fought in new ways…

02:46

Of course, like every amazing new technology, the telegraph was eventually made obsolete. [A telephone and the telegraph machine fighting]

02:50

By the end of the 19th Century, a new fangled doo-hickey called the telephone was already

02:55

taking over…

02:56

In much the same way real floating hover boards will one day replace these fake ones with [Man on a hoverboard flies past man on a segway]

03:01

wheels…

03:02

Hey, a boy can dream.
