Today, we’re beginning a brand new series called The History of Microsoft. Travel with us back in time as we discover the roots of one of the world's most important technology companies. Using rare video and photos we bring you the heart of Microsoft's struggles and successes. Year by Year. Every Thursday we will air a brand new episode beginning with 1975 where "The History of Microsoft" all began.
We hope you enjoy this historical journey.
1975 History of Microsoft Timeline:
January 1, 1975
The MITS Altair 8800 appears on the cover of Popular Electronics. The article inspires Paul Allen and Bill Gates to develop a BASIC language for the Altair.
February 1, 1975
Bill Gates and Paul Allen complete Altair BASIC and sell it to Microsoft’s first customer, MITS of Albuquerque, New Mexico. This is the first computer language program for a personal computer.
March 1, 1975
Paul Allen joins MITS as director of software.
April 7, 1975
“Altair BASIC – Up and Running,” declares the headline of the first edition of MITS Computer Notes.
July 1, 1975
Bill Gates' and Paul Allen's BASIC officially ships as version 2.0 in both 4K and 8K editions.
July 22, 1975
Paul Allen and Bill Gates sign a licensing agreement with MITS regarding the Basic Interpreter. The name Microsoft has not yet been chosen, and Microsoft is not yet an official partnership.
July 29, 1975
In a letter to Paul Allen, Bill Gates uses the name "Micro-soft" to refer to their partnership. This is the earliest known written reference.
December 31, 1975
The 1975 year-end sales total equals 16,005 dollars, as detailed on Form 1065 U.S. Partnership Return of Income.

This footage is awesome, It's so cool seeing the first version of BASIC

My favorite part of the interview is when Bill's bragging about how he reduced the number of bytes for the loader that Paul had built
Congratulations!
Looking forward to the next episode.

Thanks for supporting this show everyone. There is lots of great footage like we see in 1975 in the years to come. It's really pretty amazing when you sit back and listen to Billg talk about how it all came together. It's good to be a part of the channel 9 community. Is there an initiation or anything? Nevermind. That scares me.

Can't wait to see the rest.
If you haven't already seen it, watch "Triumph of the nerds" and "Nerds 2.0.1" from Robert X Cringely. They are great documentaries about the birth of modern computing and the Internet.
man that's awesome, I like when Bill mention that the first bootstraper was 46 bytes and then later he wrote one on 17 bytes.
Can you imagine sitting in your office facinated with this computer and flipping switches all day long? we have come a very LONG way, I am sure people would be making fun of us in 100 year from now for having desktops with only 2 and 4 cores.
Going from holes punched into cardboard to enter instructions into the computer, all the way up to Microsoft Windows 7 technology.
Congrats Microsoft.
Mine's smaller than yours.
Wait, that didn't sound right....
Awesome, thank you Tina to share this. The most amazing thing I like that Bill & Paul invent Basic in one month or less! I liked that bill is still having that Altair 8800 also I like when Bill enhanced the loader and reduce the number of bytes for the loader lol.
Congratulations!
i wish i can work there......
Could the high quality WMV be reuploaded please? The current one is broken.
Sorry to be grumpy, but I'd much prefer a version targeted at programmers, without the instant-brainwipe background noise and with a presenter who looks and sounds like she'd code circles around me. Just a thought.
I think I bought my 8K Microsoft Basic rom for th Rockwell Aim 65 in 1978. To me (in Europe) Microsoft already was an institute, an authority. But Basic was Texas Instruments calculators and school (arrays and mathematics), Forth was HP reversed polish notation, electronics and fun. I studied for weeks, but - just as with the 8K Monitor rom of the Aim 65 - I couldn't make the connection between the assembly opcode and what was going on functionally. It just went over my head. The 4 K Forth rom was easy: if you understood defining words (especially the Next-interpreter) you understood it all. Besides, most of Forth was written in Forth.
I think what killed Forth was that it was Open Source (the term then, slipped my mind). I wonder what would have happened if Bill had gone for Forth in those days. I think, we would have had totally different boundaries regarding opcode, operating systems, languages, applications etc, than we do today. A lot of what the CLR, managed code, .Net Framework and the like is meaning to us, would have been intrinsic in my view. Anyway, Microsoft today is an ashtonishing feat, with a lot more to come probably.
It is very interesting to see the beginning of this now Empire of a company. I remember when I was a kid about 10 years old or so and got my first PC for Christmas. That system is ancient now but I still have pictures of it. It is truly interesting how far technology has come since the mid/early 80's.
Nice episode
waitiing for another one 
Good article....
Wow it's really great to see that this all started the year i was born. Going from holes punched into cardboard to enter instructions into the computer, all the way up to Microsoft Windows 7 technology. Congrats Microsoft.
Amazing his persistance. I don't think it was ever about the money.
This is a great article. Quite informative.
Nice video. It's nice to see how it all started.
@Dan:Bang
Great piece of article , thank you for sharing this with us !

Great idea for a series of videos, look forward to seeing all of them.
And to think when I went to college, they were still handing out handwritten receipts for our tuition payments. Long ago...

You have to understand that in the early days of micro computers every byte counted. The was limited memory and limited space for storage.
Great hystori of Microsoft. Bill Gates change the world. This video is very god. This is a great article. I also working in software industry, I am programmer. Congratulations from Romania!!!
great...... histori of Microsoft and now the next name of technology has become d Bill Gates.............
Great post Tina, really interesting stuff!
Looking forward to your next post
amazing, awesome, a leyend.....
Legend !
