Paper media is on the decline and you're talking about a new magazine? Bad plan. I still subscribe to one magazine and get one free with my SCI membership. Both are published quarterly and, honestly, I haven't cracked the cover on either since early July and even then I was at least two quarters behind. Maybe some people have more time than I do, but the three hours between when my kids go to bed and when I hit the sack have plenty of our demands without feeling bad that I'm not reading yet another magazine.
Now what I do consume, by the boatload, are podcasts. My daily commute is 45 minutes each way and ere are six or seven podcasts that I listen to either every episode or regularly enough. Short ones are an hour long and long ones can top three hours. I can listen while I'm driving, working around he house...anywhere. That's my preferred way to consume media these days. I barely even listen to music anymore.
this. im from the old school and unless there is no power for a while i do not see reading a hunting outdoor magazine made of paper, especially the one trying to sell me some stuffs that i do not need ... and your project while good will be hard even with ads in.
good luck.
