A lot of magazine content is still not published online although there is a long tail market.
"Collaborative magazine paywall" is one of my Top 10 Media Innovation Ideas. I'm publishing one media innovation each day during the ten first days of October.
What was I proposing? Oh, yes. Just a Piano media style "magazine Spotify" especially for those magazines who are not online yet.
Why for them? Because they know that they should be online but they don't know how. The others are already playing their own game and complaining about YLEs very, very effective paywall.
The core point with this idea is that is should be sold as a source of additional revenue to the magazines. Now, when they are not putting their content online, they loose money. Not much, but some. These magazines are afraid of cannibalizing their sales, but how many magazines they sell a month after the mag has come out?
The digital distribution of these magazines doesn't have to be instant. But it has to be based on a subscription fee and the fee has to be cheap. The subscription fees would be divided between magazines based on, you guessed it, reading time, with a small portion of the revenue staying with the paywall operator. (there is also an unfair way to do this, paying magazines per fixed reading time rate and keeping the subscription fees, which would be very profitable if the subscription becomes a thing - compare to spotify, again).
