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.

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

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…

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]

wheels…
