I just saw the numbers for sales of cameras i Norway, and the total
number of cameras sold in Norway in 2008 was 542 000, and of that
DSLR sales was over 107 000. That means that DSLR is about 20%
of the total numbers of cameras sold in Norway.
What is the percentage in other parts of the world?
IDC has a report
on digital cameras, but it is not for free. I wasn't able to find free sources with quick googling.
