zortech - symantec - digital mars

[Ali]

Out of curiosity

What is the history between dmd and symantec
I was able to find few things online

I know that there once was a company called zorland, which later 
becamse
zortech

Zortech, created c/c++ compilers
Symantec tookover zortech, to get into the compiler business

Walter Albright, was part of Zortech (not clear if he was the 
founder or an employee)

But this is what I was able to find ends

How was dmd started in Symantec, did they sell a D compiler for a 
while, did they use it internally as a competitive advantage, 
what was Symantec plans for D?

Just curious .. if Walter care to share, or if someone else knows 
more than I do, please share
