What Remains Unclear: The September results don’t indicate whether NBC’s growth will translate into a sustained challenge to ABC across the full 2026-27 season. Additionally, the networks’ ratings can shift based on major news events, scheduling differences, and changes in Nielsen’s measurement methodology.
What It Means: ABC enters the new broadcast season with another year at the top of the evening news race. However, NBC’s September performance gives NBC Nightly News a strong audience-growth story as it continues closing the gap in the key demo. NBC reported that the program averaged 6.6 million viewers during the third quarter, its largest third-quarter audience in six years.
