I am trying to find some data on how the sales volumes of EXTERNAL
camera phone attachments have developed since they were launched.
These were the  devices that you plugged into your phone; nowadays
they have been largely replaced by mobile phones with integrated
cameras (I can find lots of data on these).

All I want to know is for each year (I guess starting in 2000 or so
when they were launched), the number of units that were sold. If you
have a geographic breakdown of any sort (e.g. how many were sold in
Europe vs. Asia. vs. the America) that would be useful. I don?t need
any special report ? a simple email with years and million of units
(with source data attached) will be fine.

I do need the source data to justify the numbers.

Thank you!
