[Licensing Deep Dive]
0:02
Licensing is a relatively simple but incredibly powerful concept.
0:04
And it's vital anyone working with the web understands it.
0:09
When we talk about licensing what we're basically saying is permission.
0:14
We're giving or receiving permission to use something.
0:17
The government gives you a license to drive, for example.
0:22
You have to promise to abide by a set of rules that they give you in order to keep using that driver's license.
0:25
But as long as you do, you're all good. They won't take it away from you.
0:31
So a licensee, the driver in this case, and a licensor, the department of motor vehicles,
0:35
agrees to a set of terms that allow the licensee, the driver, to drive a car.
0:42
This is basically how most licenses work.
0:48
Someone gives you permission to use something that they created, own, or control.
0:51
I mean Nintendo aren't the only ones manufacturing every single thing in the world that has Mario on it, for example.
0:55
Toothbrushes, pencils, backpacks—all of those are made by different companies that obtain a license from Nintendo
1:01
to use Mario on their products.
1:08
You license things all the time without realizing it.
1:11
I mean be honest, whenever you install iTunes you never read the EULA, do you?
1:14
You just click "Agree".
1:19
What does EULA stand for?
1:21
End User License Agreement.
1:23
Every time you click that "Agree" button, you're agreeing to the license terms.
1:26
You don't own iTunes.
1:31
You are just licensing a copy of it for your personal use.
1:34
So all that text, everything in there, you're saying "okay" to that license agreement.
1:38
Which means you agree to, among other things,
1:43
and I quote "not use these products for any purposes prohibited by United States law, including, without limitation,
1:46
the development, design, manufacture or production of nuclear, missiles, or chemical or biological weapons."
1:54
Now I know what you might be thinking.
2:03
"But iTunes is free. Well why do I need to license it?"
2:05
Well to license something does not necessarily mean to pay for it.
2:09
There are lots of different types of licenses.
2:13
Many licenses are accompanied by payment of some kind,
2:16
but there's also a great many free licenses out there.
2:19
You might have heard of Open Source software, Creative Commons, MIT Licenses, GPL, even Microsoft has their own free licenses.
2:23
Ultimately any two parties, whether people or companies, can write and agree to licenses.
2:32
Most licenses are written by lawyers, but there's no law saying that they have to be.
2:39
And there's no specific way they have to be written or formatted.
2:44
As long as both parties agree to it, you've got yourself a license.
