Abstract
The Nationwide Diary–Method Survey on Cross–Platform Reach is a public opinion survey that measures the reach, or the percentage of individuals who use various contents and services provided by broadcasters—not only TV and radio broadcasts but also recorded programs, social networking services, online videos, and websites—at least once during a given week. NHK has been periodically conducting this survey.
The authors classified the reach of contents and services provided by broadcasters into three categories: "real-time" (via broadcasting),"time–shifted," and "internet" (via telecommunications). In 2024, the “real-time” reach was 87.8%, “time-shifted” 50.6%, and “internet” 36.7%, with the total reach (using any of the above) of 92.0%. Among them, the reach of “recorded program”—a type of the “time-shifted” reach—has decreased from the 2021 survey, and the reach of “free videos (official)” (viewing TV programs, officially available from broadcasters, via streaming services such as “NHK Plus” and “TVer”)—a type of the “internet” reach—has increased from the 2021 survey. The percentage of connected TV (CTV) rose to 50% for the first time. With these changes in the situation, the survey also shows that the use of catch-up services is spreading to replace recorded-video-viewing.
