I am currently writing a report, I would like to make a claim which I am struggling to back up:
The volume of image data transferred digitally has increased as the internet has become more popular and fast download speeds has become more easily accessible.
Of course I don't actually know this claim to be true. However, I think it's a reasonable claim given that the number of gadgets people own seems to be increasing (at least where I am from), as does the global population and there are developing countries working on high speed internet infrastructure.
Does anybody know of any data that could help me back up my claim? For example data where volume of image data being transferred is measured over at least, lets say 10 years would be great!
