Increasingly, delayed viewing must be factored in by networks trying to decide which shows to retain and which to reject, Mr. Moonves said. He pointed to how many viewers were added by “Hawaii Five-O” each week: more than 2.4 million. “That is a big, big number,” he said.
What the “live+7” performance does not do is make more money for the networks. The accepted system of advertising sales continues to be based on what is called a “commercial+3” rating: that is, how many viewers watched the commercials within three days of a show’s first broadcast. (Advertisers do not want to pay for viewers who skip through all the commercials.)
