It might be possible. This article from the Inquisitr (via @InShot) breaks down a very exciting initiative from PayPal. They want people to be able to easily make purchases using their remotes. I had kind of ruminated on the possibility of this during NewTeeVee Live last week. This seems to make it closer to being a reality. It could definitely change advertising. From an indie filmmaking perspective to give a person the option of purchasing one’s film right after watching would be nice.
