Editor Eric Flint notes that the online magazine Jim Baen’s Universe is closing after the April 2010 issue. Says Eric:
In a nutshell, we were simply never able to get and retain enough subscribers to put us on a sales plateau that would allow us to continue publishing. From the beginning, we were too dependent on the income from the Universe club. The Club’s purpose was to provide the magazine with a much-needed initial surge of income–which it did indeed provide–and then, after the first year, to continue as an important but subsidiary source of income. Instead, the Club wound up being the source of about half of our annual income, from beginning to end.
It also looks like they are doing right by their writers and paid subscribers, so nobody needs to worry on that front.
