There are probably more answers to this than there are people who were
paying attention at the time, so take any answers - including this one
- with a grain of salt.

Before the microcomputer revolution, IBM was the 800 pound gorilla in
the computer market. They pretty much owned the large company
mainframe market.  They weren't quite so dominant in the minicomputer
market, but were still a major player. The PC market was miniscule,
and mostly ignored by the mini and mainframe makers.

To get an idea of how dominate IBM was, that they ran ads claiming
"Nobody was ever fired for buying IBM". I've been told this claim is
no longer true. Likewise, they used to be quite proud of having
*never* fired anyone. If you weren't performing, they'd quit giving
you raises/promotions, and start relocating you regularly - leading to
the "I've Been Moved" moniker for the company. If you left and later
recommended hardware other than IBM, you could predict that the IBM
sales reps would make negative references to your having left IBM.

VisiCalc shows up and legitimizes PCs for office work. However, there
was no PC from IBM, so few IT managers would approve company money for
purchase of a PC, so the market stayed relatively small.

Enter the IBM-PC. It's clearly inferior to hardware already on the
market and cost far to much. The largest PC retailer of the time -
ComputerLand - figured they'd never be able to sell one. However, it's
from *IBM*. So all those IT managers start buying them, because
"nobody was ever fired for buying IBM." The demand outstrips the
supply, the clones start showing up, and the revolution is on.

The machines came with an OS called PC-DOS. You could also get
CP/M-86, the 8086 version of the previous dominant OS, but it cost
extra without providing any extra functionality. PC-DOS came from
MSFT. IBM had apparently wanted to purchase it outright, but Gates
convinced them to pay a percentage instead. In doing so, Gates stole
the revolution from IBM.

By maintaining ownership of MS-DOS, Gates could sell a "generic"
version - MS-DOS - for the clones.  Since the business market was on
IBM hardware, the clones needed to be able to run software written for
that market. Radio Shack created a "better-than-IBM" compatible -
better graphics, etc. - and it died because the available software
wouldn't run on it properly. In other words, even then, if you
couldn't run the popular software, you were pretty much dead.

Thus, IBM's dominance in the mainframe market(*) translated to
dominance on the PC hardware, but they were using MSFT software, thus
giving MSFT software dominance.

FWIW, Gates sold IBM a product he didn't have. He then went out and
bought QDOS - the Quick and Dirty OS - from SCC, which had written it
for their 8086 S-100 boxes because Digital Research kept delaying
CP/M-86.

I'm sure others will offer corrections.

(*) FWIW, I've seen claims that IBM's hardware dominance came from the
IBM 360 series. It was the first computer to have both word operations
and byte addressability, making it the first computer that could
reasonably do both business and scientific computation. Being able to
buy one machine instead of two is a serious advantage, and it
obviously succeeded.
