THE DEAL THAT MADE MICROSOFT MICROSOFT
In 1980, Microsoft was already making money.
But it wasn't the Microsoft we know today.
Then IBM came looking for something Microsoft didn't really have:
An operating system.
And what happened next changed the software industry.
IBM NEEDED AN OPERATING SYSTEM
IBM was building what would become the IBM Personal Computer.
The company had already approached Digital Research about using CP/M, one of the leading operating systems of the time.
The negotiations didn't work out.
So IBM turned to Microsoft.
There was just one problem:
Microsoft didn't have the operating system IBM needed.
MICROSOFT FOUND ONE
Microsoft knew about a small company called:
Seattle Computer Products.
Its engineer Tim Paterson had created an operating system called 86-DOS for 8086 computers.
Microsoft initially licensed it for $25,000.
Then Bill Gates and Microsoft realized something much bigger was happening.
If IBM's PC succeeded, an operating system compatible with it could become extremely valuable.
So Microsoft bought the rights to 86-DOS for additional money.
It was then developed into what became MS-DOS.
THEN CAME THE REALLY IMPORTANT PART
Microsoft didn't simply sell the operating system to IBM.
It licensed it.
And Microsoft kept control of the software.
That meant Microsoft could also license MS-DOS to other computer manufacturers.
This was the crucial move.
IBM could sell the famous IBM PC.
But Microsoft could sell the software running on thousands of machines.
One deal → many manufacturers → millions of computers.
IBM CREATED THE MARKET
On August 12, 1981, IBM launched its Personal Computer with Microsoft's operating system.
IBM's name gave the personal-computer market enormous credibility.
And MS-DOS suddenly had access to that market.
But something even more important happened afterward.
Other companies began making IBM-compatible computers.
And they needed operating systems too.
Microsoft was ready.
THE BUSINESS MODEL WAS THE SECRET
Imagine Microsoft had sold the operating system exclusively to IBM.
Microsoft might have made a lot of money.
But its growth would have been tied to IBM's PC business.
Instead:
IBM PC
↓
MS-DOS becomes familiar
↓
Other PC manufacturers appear
↓
Microsoft licenses MS-DOS to them
↓
More computers use Microsoft's software
↓
Microsoft becomes the software standard
That is a completely different business model.
MICROSOFT DIDN'T NEED TO BUILD EVERY COMPUTER
This is what made the deal so powerful.
Microsoft didn't need factories.
It didn't need to manufacture keyboards.
It didn't need to build hard drives.
It didn't need to sell the physical computer.
It could make the software once and license it repeatedly.
The same basic product could generate revenue across an entire industry.
That is the power of software licensing.
THE NUMBERS TELL THE STORY
Microsoft entered the operating-system business in 1981.
By the end of that year, Microsoft reported sales of about $17.3 million.
The company had found a position at the center of a rapidly expanding PC ecosystem.
And MS-DOS helped turn Microsoft from a software supplier into something much bigger:
a platform company.
THE PART PEOPLE OFTEN GET WRONG
Microsoft did not invent the original operating system from scratch.
86-DOS was created by Tim Paterson at Seattle Computer Products.
Microsoft first licensed it, then acquired the rights, worked with IBM on adapting it, and developed it into MS-DOS.
The genius wasn't simply:
“Microsoft bought an operating system.”
It was:
“Microsoft made sure the operating system could become the software layer underneath an entire PC industry.”
SIMPLE IDEA
Sometimes the most valuable deal isn't the one that gives you the biggest customer.
It's the one that gives you the right business model.
IBM helped create the market.
Microsoft positioned itself underneath that market.
And instead of owning one computer company...
Microsoft's software could run on thousands of them.
MAACAT PERSPECTIVE
Microsoft didn't need to own the machine.
It needed to own the layer everyone needed.
That distinction helped turn a small software company into one of the most powerful technology companies in history.
