Who would buy Hulu? We know that its backers - NBCU (Comcast/GE), Fox (News Corp), and Disney/ABC - are not making as nearly as much money off of it as they want to. As a result, if they sell it off they are unlikely to support their content being on there even with the fees, since the fees Hulu is able to generate are not adequate.
So with that in mind as soon as Hulu loses its media backers it appears doomed to go straight into the ground, who would pick that up?
