Last fall, Marco Arment launched a general interest magazine. It's called, aptly enough, The Magazine. Writers are paid $800 per article. There are no ads. Until recently, it was available only via iPhones and iPads. Astonishingly, it's already turning a profit.
Arment walked me through the numbers. He has 25,000 subscribers who pay $1.99 a month. Apple takes a 30 percent cut, leaving Arment about $35,000 a month.
