"Shorter commercials and shorter pods are going to be better. We have to charge more to the advertiser for that, but it's going to be better for us and better for them in the long run," Greenblatt told CNNMoney's Dylan Byers at the Milken Conference last week.
In an effort to attract eyeballs away from ad-free streaming services, the NBC exec wants to shorten the first commercial break in his network's shows from as long as 5 minutes to just 1 minute, with the idea that doing so will keep the viewer engaged. Despite advertisers being charged more for it, he said that commercial break is "more valuable to them because the consumer gets more out of it because they're not barraged with stuff they normally would tune out."
Greenblatt admitted that NBC's ratings and revenue are dropping, but said he's seeing success in other aspects of the business.
"Thirty to 40 percent of viewing of our shows is off the network, so as long as I can follow that viewer to Hulu, which we also own, or other platforms, it's OK with me," he said. "As long as I can track how many of you are doing that and I get some monetization."
