Looking for plans on how to take a free printed publication to paid digital subscription
I'm currently working with a free to the public printed publication that is seasonal and dishes out only 3 volumes per year. It is in it's second year - with number 5 about to come out by the end of the month.
The publication itself is informative on topics relating to my geographical area. There are about 25,000 copies that go out per issue.
The magazines themselves contain topics that are considered to have a "long shelf life" - meaning some people will actually collect these magazines as they provide great information for others who may be researching a specific topic.
The goal of the publisher is to transform the magazine into a paid digital subscription so the magazine can be monetized beyond the current advertisers who support it.
Anyway, I'm looking for alternative blueprints or plans on the best ways to do this and best companies/venues to be working with.
There are already plans to include much more information as well as multimedia in the digital subscription version.
Has anyone here done this before or know someone who currently does this?
