A single, high resolution jpeg image is rarely above 100 megabytes. This would
imply something like 4k x 4k pixels, lots of detail and a low compression factor.

I would guess the normal porn image is way below this. (The message does not
require THAT good an image to convey).

I do have some map scans that go to 150MB, but they are exceptions.

Audio is from 120 k/minute (phone grade) to 40 m/minute(5.1 high resulution).
Broadcase audio is normally around 200-300 kbit/second, or 1.5 - 2 megabyte/minute.

Video is another matter. Plain SD compressed is 4G/hour. HD can go to 15. 1k
to 40, 4k to 100G/hour. That can make a significant dent in storage.

Half of all pictures have been taken the last 2 years. Half of all video
(in terms of resolution) has been taken the last 18 months.

So we are at doubling rates of ~20 months. Which the bandwith growth figures
of the Internet seem to bear out; at ~44% yearly growth.

The copper links to homes and small offices are saturated. But bring in fiber, 
and you can double every 20 months for nearly a century. The national 
backbones (from US to smaller nations like NO/SE) can still increase traffic
by around 100 times without laying much new fiber; and by another 5-10 with
embryoninc technology seeing the light of day right now. (like 500G colours).
