I really wish Visual Basic would be open sourced from Microsoft, so the community would revive it. I still have fond memories programming with VB and the productivity it allowed - it had it's issues (oh, man...) but also made programming accessible.
VB6 is dead though, everyone wants COM to die so even if MS open sourced it there's no real reason to continue putting effort into it. There are alternative that work reasonably well though, like Gambas (open source).
The main reason is the sheer amount of software out there that businesses rely on to run their business, which they might not even have the source code to. Those that do have the code do hire people to maintain and extend the applications (shades of COBOL there).
It wouldn't surprise me to find out that new VB6 applications are being created - lots of people love it and loved using it (though I personally preferred VB5, because the compiler was separate from the rest of the system and could be used at the command line). VB.NET was widely viewed as a travesty to the language; some moved to C#.
What is strange is how few of these programmers seem to be aware of Gambas (and similar "VB-like" languages). I moved away from Windows at home in 1995 and move on to Linux; over time I became aware of other BASIC programming languages, but I moved away from BASIC as well, though it will always hold a place in my heart, since that's what I started out with.

So researchers already used to VBA, usually get IT to install VB.NET and go from there.
However I have started to see a trend of them moving into R.
Of course, Visual Basic lives on (as part of the free-as-in-beer Visual Studio).
