Disruption or Revolution
So let us assume this for a second: Larry Ellison wakes up one morning in his luxury San Francisco house, for once all alone in the building with the rest of the family in the Hawaii house. He gets out of bed and goes to the kitchen to make some breakfast. He decides on a cappuccino and some oatmeal porridge, he is a bit of a health nut after all. The coffee is prepared for him by his automatic machine that he imported from Switzerland and he micros his porridge and sits down by the bar in the kitchen to eat it. He opens the newspaper and starts reading it, but his mind drifts away, he had been dreaming something just when he woke up and he tries to remember what it was, and then, in the middle of half reading the editorial in the San Francisco Chronicle and half thinking about his recent dream he gets it.
The next step for the huge company that he once founded and now is the CTO of was what he was dreaming about and he now knows where Oracle will head. He feels invigorated in a way that he has not felt for a long time, maybe last time was as far back as 1977 when he decided to co-found a company to build the worlds first commercial SQL-based relational database system.
Larry finishes his breakfast quickly, leaves his house in his bright read Ferrari and drives along the 101, ever so slightly too fast but still so slow that the V12 equipped Ferrari is merely idling. He gets to the huge Oracle Parkway head office and heads up to his secretary, still carrying his expensive, elegant and lightweight leather briefcase. "Get all available execs to my office. My execs that is." His secretary gives him a puzzled look, what is going on, he looks so upbeat, she thinks, but in a very positive way, he seems to be gleaming with enthusiasm as he continues into his office.
Two hours later the available team of executives are gathered in Larrys office, some of them who hasn't been here many times before admire the view of the Bay Area through the glass wall behind Larrys back. Larry looks at them with a smile, something the team is not used to so they know something is about to happen. "I have an idea. Actually it is more than an idea, it is a plan and an order. Exactly how this plan will be implemented is up to you, but take it as an order that it is going to happen. If you don't agree with me, that is fine, there are many other companies out there that you can work for."
Larry now has the attention of everyone in the room, they look at him and wait for the next comment from him. Larry stays quiet for a while, and then he raises his voice ever so slightly. "If you don't want to be part of this big change, the biggest in the history of this company, then you are free to leave the room. There will be no hard feelings, I just want positive vibes, if you feel like being negative you are free to go somewhere else in the Valley. I will not oppose that and I wish you all the best if you don't want this. But make up your mind right now as after I have told you what we are going to do, I expect you to stay around and positively support the journey that we are about to embark on. OK".
The team of C-level executives look at each other, and then again at Larry, who keeps quiet. Then everyone looks at Larry again and all are still quiet. 30 seconds pass in silence, then Larry talks again, real quiet so everyone has to listen real hard. "SQL is about to die, and we are to ones that will kill it". The execs look at each other in amazement and Larry talks again "It stops right here, right now". Everyone's eyes open wide and Larry raises his voice "SQL sucks. SQL will be gone from all Oracle products within a year. No SQL support in Java, Oracle database will be gone and replaced. All SQL will go away and it starts right now."
The story above might be interesting, but it has very little to do with reality, this would never happen, right? If it DID happen, would it count as Disruption? Not really Evolution I guess no, I would really count this as Revolution and those don't happen often unless you happen to live a country in Central America I guess. But they DO happen even in the world of IT, let's roll back the time to the early 1960's, when the Vietnam war ongoing, JFK was still alive and mini-skirts were just around the corner. At the office of the biggest name in computing, IBM, there was a worry, but sales wasn't one of them, IBMs computers sold like hotcakes. Not, the issue was that IBM at the time had some seven different lines, yes seven, of computers, all incompatible in every conceivable way. It has to be understood that in those days, a computer was to a very large extent bespoke, software was mostly an afterthought and was also incompatible not only between machines from different IBM series of computers but also between different individual computers, if one had a different printer than the other, rewrite your code etc. At the same time, IBM computers were selling and the most popular among IBMs many series of computers was the mid-range 1401 series of which thousands were produced of this machine with roots in the 1950's. A key component was that the 1401 was rather complete, it did not only have CPU and memory but other parts were also part of the system such as tape drives, printers and cupholders (just kidding). This sounds obvious today but not so at the start of the swinging sixties. And a key component of the 1400-series was the 1403 line printer. This printer was the fastest in the world and it came with the 1401 computer. So if you wanted the best and fastest printer in the world, you had to but a 1401 computer, there was no other way. And if you had some other computer and you wanted to print on the 1403, then you had to put that on a tape or something that you brought (physically, by hand) to the 1401 to print on the 1403. A mess.
Something called the SPREAD group at IBM began to look into this issue of all these different architectures in 1960ish and they were ready by the end of 1961 when they produced a report. This report said something similar to what Larry said in my made up story above, scrap everything we have and start again. And IBM did just that, to everyones surprise. In 1964 the System/360 series was announced and it came to revolutionize computing. From a technology point of view, if wasn't spectacular, but from the point of view of how the technology was applied, is was spectacular. System/360 was a series to computers, small to large and as such could
span the "whole circle" of computing needs, hence the 360-designation. And it came to change and influence IBM to this day and eventually wipe most of its then competitors off the map.
So once the 360 was delivered, which took longer than anyone expected after the announcement as, and this was quite unexpected back then, writing the code for the operating system(s) took waaay longer than expected (see the book "The mythical man month" for details), everything was hanky panky (technical term meaning hanky with a slight touch of panky added to it). One minor issue remained, and stayed to this day, the 1401 emulation. Yepp, this turned out to be an issue in the long run as really old programs, dating back to the 1950's would still run. And run. And run. And this is why software that was developed in the 1950's continues to run to this day (I'm not kidding here) and this is also a reason to why the 360 and it's newer siblings continue to be used, to this day.
In summary, with the System/360 IBM took a bet, and they more or less bet the company. IBM was largely all computers at that time, the privious profitable punch card business was in quick decline. But the bet paid off, big time.

Back from the dust-filled basement of computer history.
PS: System/360 introduced many new things that we stil use today and take for granted. The "byte" first came around as a term with System/360, which was 32-bit and 8 bits was convenient. That any printer works as well with any computer also started with System/360, although the common technology or printers being the #1 thing to drive sys admins crazy was still established at the time of the System/360 release and is a tradition that continues to this day.
