I'm a newbie on the forum, although I've kept an eye on it from outside for many years.
First thing to say is, the comments especially in the first and third posts on this thread are very flattering (and indeed are the main reason I decided to jump in and join the discussion)!
Beyond that, there are some very interesting views about how the internet is killing the print magazine industry. To a large extent they're absolutely right, but the full picture is actually more complicated.
The internet can be a superb source of information, but magazines have an advantage in that they "curate" material and present it to the reader as a package of "concentrated goodness" — i.e. a quality magazine or journal will (a) save the consumer time because he/she will not have to trawl through multiple online sources for information and will (b) provide information that has been filtered through an editorial team and can therefore expected to be accurate and trustworthy. One of the biggest questions we should all ask ourselves when looking at apparently factual information on websites is, "can I trust this?".
The main threat to magazines from the internet is not so much that the internet can provide the same information for free (there's lots of info, especially historical material, that is not on the internet and is never likely to be), but that the internet competes with magazines for people's time and attention. The same can be said of the proliferation of TV channels — in the days when in the UK we only had four channels, we probably had a lot more time to read magazines.
On the upside for magazines/journals, the internet is a godsend in that specialist titles can reach far into special-interest communities without having to spend a fortune on advertising — if enthusiasts all round the world can find us by Googling etc, we can get our message out there much more efficiently, quickly and cheaply, which is an enormous aid to the growth and survival of such titles.
So the internet is killing some magazines, but for specialist niche titles it is usually doing much more good than harm.
I hope the above ramblings might offer a fresh perspective!
