Full disclosure, I work at PressReader. But it surprises me sometimes when we're not mentioned in these conversations. We do huge business internationally, have millions of active users, have been profitable for years, and are growing at an absolutely insane rate. It's a win-win business model because readers get content (often for free since it's sponsored by a brand they're a customer of), publishers make money (we pay royalties when their content is read), and brands have the opportunity to offer something tangible and personalized to their customers.
