Moonves said each subscriber is worth about $4 a month to the Eye in terms of advertising revenue. At present CBS All Access charges a $6 monthly fee for live streaming of the network and VOD access to current and library series with advertising included. The company is weighing options for offering a $10 monthly version that would be ad-free, similar to the tiered offering from Hulu. “We’re thinking about it,” he said. “There could very well be a $9.99 product out there.”
