Sales of the Commodore 64 itself appear to have peaked (along with sales of 8-bit home computers in general) around 1984, though continued for another decade after that.
I'm curious about sales of software for the machine (all formats: cartridge, disk and tape). I would expect that to peak somewhat later (because people who buy the machine, might keep buying software for several years after that).
Has anyone compiled statistics of sales by year for it? Or for other platforms, that might allow an attempt to extrapolate?
