Overview

• Effective Sept. 1, Nielsen is asking broadcasters, networks and streamers to base public ratings claims on Big Data + Panel under its new press policy.
• Nielsen says results typically deliver to clients within two to three days after a premiere, with a specific exception to expedite single‑day live‑event reporting.
• The dataset blends its existing panel with viewing from 45 million households and 75 million devices via partners including Roku, Comcast, Dish, Vizio and DirecTV.
• First‑party streaming data for live events is incorporated to align measurement across platforms and support audited, accredited streaming comparisons.
• Planned upgrades include faster weekly streaming rankings and a significant expansion of out‑of‑home coverage after an initial rollout proved too limited.
