To clarify, I meant stopped growing at its previous rate. I can't find any data further than 10 years old ATM (which is within its mature growth period), but have a look at its stock price. Note the exponential increase before 2000. https://www.google.com/finance/getchart?q=MSFT&x=NASD&p=40Y&... While there was a stockmarket boom and crash then, you can see that MS had been growing madly for a couple of decades previously.
Why the downvotes? If you look at the stock price over the MAX range, you can see exponential growth until 2000 - then it went sideways. Stock price represents the opinion of investors. It's not just programmers.
