Microphones: What is the relationship between the companies DPA and B&K?

I do not have a clear view but here's what I think the situation is:

B&K shut down their microphone division some years ago
DPA is part of, but not all of, the old B&K microphone division
DPA is the recording / musician product line, but they do not make 'measuring microphones' as such
The old B&K measuring microphone line (example: the 4133) is not made by anyone any more and never had any successors

...Do I have that right? Thanks.
