Boxee, the popular online video and TV streaming service, announced that it will be adding a payment system to its streaming platform. The payment system will launch over the summer and will allow Boxee users one click access to paid content including TV shows, TV channels, and movies via a pay-per view or subscription based model. They are currently trying to court content partners willing to make their entertainment assets available to Boxee customers and are offering content owners the ability to package and price the content as they see fit. Boxee, of course, will take a small cut from each purchased item, thereby generating a new revenue stream for the start-up company. Current Boxee users who eschew paid content can breath a sigh of relief as Boxee has publicly stated that the paid content will be optional and Boxee will remain a free service with access to free and ad-supported content. Drinks all around.
