When he was in the eighth
grade, the Mothers Club at
the school used proceeds

General Electric (GE)
computer for the school's
Gates took an interest in
programming the GE system
He wrote his first computer
program on this machine: An
implementation of tic-tac-toe
that allowed users to play
games against the computer.
Gates was attracted by the machine and how it
would always execute software code perfectly.
When he reflected back on that moment, he said,
"There was just something neat about the machine.
One of these systems was a PDP-10, which banned
but Gates, Paul Allen, Ric Weiland, and Kent Evans
were caught for exploiting bugs in the operating
At the end of the ban, the four students offered to
find bugs in CCC's software in computer. Rather
than use the system via Teletype, Gates went to
CCC's offices and studied source code for various
programs that ran on the system.
The following year, Information Sciences Inc.
hired these four students to write a payroll
program in Cobol, providing them royalties. After
his administrators became aware of his
At age 17, Gates formed a business partnership
with Allen, called Traf-O-Data, to make traffic
counters based on the Intel 8008 processor.
Gates graduated from
Lakeside School in 1973, and
was a National Merit Scholar.
He scored 1590 out of 1600
on the SAT and enrolled at
Harvard University at
While at Harvard, he met
Steve Ballmer, who would
later succeed Gates as CEO
of Microsoft (from 2000 to

pancake sorting as a solution
to one of a series of unsolved
problems in lecture. Gates'

Gates did not have a
definite study plan while a
student at Harvard.
Gates remained in contact
with Paul Allen, and he
joined him at Honeywell in
In 1974, MITS Altair 8800
Computer came into
Gates contacted the
creators of new
microcomputer, to inform
In reality, Gates and Allen did not have an Altair
and had not written code for it; they only wanted
to got MITS's interest.
MITS president agreed to meet them for a demo
few weeks later.
During this time, Gates and Allen developed an
Altair emulator that ran on a minicomputer, and
then the BASIC interpreter.
The demonstration was a success and resulted in
a deal with MITS to distribute the interpreter
as Altair BASIC.
Paul Allen was hired into MITS, and Gates took a
permission of absence from Harvard to work with
Allen at MITS.
Gates and Allen had their first office named
Within a year, the hyphen was removed, and on
November 26, 1976, the name "Microsoft" was
registered with the Office of New Mexico.
Then Gates never returned to Harvard.
Launching a Revolution…
Microsoft's BASIC was popular with computer, but
Gates discovered that a pre-market copy was
being widely copied and distributed.
In February 1976, Gates wrote in the MITS
newsletter in which he asserted that more than
90% of the users of Microsoft BASIC had not paid
money to Microsoft and by doing so the Altair was
in danger to professional developers to produce,
distribute, and maintain high-quality software.
This letter was unpopular with many computer
hobbyists, but Gates persisted in his belief that
software developers should be able to demand
Microsoft became independent of MITS in late
1976, and it continued to develop programming
language software for various systems.
The company moved from Albuquerque to its new
home in Bellevue, Washington, on January 1,
During Microsoft's early years, all employees had
broad responsibility for the company's business.
Gates oversaw the business details and write code
IBM approached Microsoft in July 1980, regarding it’s
upcoming IBM Personal Computer. IBM proposed that
Microsoft write the BASIC interpreter.
When IBM's representatives mentioned that they
needed an operating system, Gates referred them
to Digital Research (DRI), instead of widely
used CP/M operating system.
IBM's discussions with Digital Research went poorly,
and they did not reach a licensing agreement.
A few weeks later, Gates proposed using 86-DOS, an
operating system similar to CP/M.
After adapting the operating system for the PC,
Microsoft delivered it to IBM as PC DOS in exchange
for a one-time fee of $50,000.
A Witty Decision...
Gates did not offer to transfer the copyright on the
operating system, because he believed that other
hardware vendors would copy the IBM's system.
Gates make it better and the sales of MS-DOS made
Microsoft a major player in the industry.
Despite IBM's name on the operating system the
press quickly identified Microsoft as being very
influential on the new computer.
PC Magazine asked if Gates were “The Man behind
the Machine?", and InfoWorld quoted an expert as
stating “It's Gates' computer".
Microsoft's company restructuring on June 25, 1981,
which re-incorporated the company in Washington
state and made Gates President of Microsoft and the
Starting of Windows…
Microsoft launched its first Operating System named
Windows on 1985 as the growing interest
in Graphical User Interfaces, and in August,
Microsoft struck a deal with IBM to develop a
separate operating system called OS/2.

Microsoft Windows came to dominate the
world's personal computer market with over 90%
market share, overtaking Mac, Operating System of

Achievements of Bill Gates…
Gates is one of the best-known entrepreneurs of
the personal computer revolution. Gates has
been criticized for his business techniques.
Starting in 1987, Gates was 32 years old and
included in the Forbes list of the world's wealthiest
people as billionaire and was the wealthiest from
1995 to 2007, again in 2009 to 2014.
Between 2009 and 2014, his wealth doubled
from US$40 billion to more than US$82 billion.
Gates is currently the wealthiest person in the
world with a wealth of US$77.2 billion.
Later in his career Gates followed number of
philanthropic endeavours, donating large amounts
of money to various charitable organizations and
scientific research programs through the Bill &
Melinda Gates Foundation, established in 2000.
Gates stepped down as CEO of Microsoft in 2000.
He remained as Chairman and created the
position of Chief Software Architect for himself.
In 2006, Gates announced that he would be
transitioning from full-time work at Microsoft to
part-time work, and full-time work at the Bill &
Melinda Gates Foundation.
Things Learned from Gates…
By his Dressing Style – It’s a common human
tendencies to pass judgement on the way others
look and dress. But doing this won’t serve you
well in business.
Gates hired smart people at Microsoft and gave
them high position for freedom to develop new
idea - A good example is Steve Ballmer, who
succeeded Gates as CEO. He is more
charismatic, showman and communicator than
Gates also knew when it was time to step aside
from the CEO role – This is not a quality you
always see among business leader.
