Assuming Fox, one of Hulu’s owners, was hoping to sell the site for top dollar, then you have to wonder about the consequences of a new plan it has announced to create an exclusive 8-day online viewing window solely for paying subscribers of authorized distributors. The new plan is a major endorsement of pay-TV operators’ TV Everywhere approach and could be the first salvo by broadcast TV networks in curtailing free online access to their programs. DISH Network is the first pay-TV operator to sign up for the new Fox plan.
