JS,
There were a couple of threads on here (not necessarily this sub-forum) last year to do with the relevance of magazine publishing in today's 'electronic age'.
The first one concerned 'Aeroplane Monthly' in particular and the second, 'Australian Aviation'.
Both threads received input from the respective magazines' managing editors.
A quick search didn't turn anything up for me but a little more time and patience might work for you.
p.s. I owe you a PM on a related subject and, 'as soon as I get my PM box sorted...'.
