NPR's Planet Money goes behind the scenes with The Magazine

Jacob Goldstein of NPR's Planet Money took a look at the economics behind The Magazine, the iPad-only publication created by Marco Arment of Instapaper and edited by Jeopardy champion and Macworld/TidBITS contributor Glenn Fleishman.

The Magazine launched late last year with essays from well-known, technology-focused writers such as Jason Snell, Lex Friedman and Harry Marks. The Magazine is published every two weeks and costs US$1.99 for a monthly subscription.

Unlike most online ventures that struggle to get off the ground, The Magazine already has 25,000 subscribers and is pulling in a healthy profit. You can read more about the financials of The Magazine and the reasons why Arment started the venture on Planet Money's website.
