Which of the following measurement tools competes with Nielsen?

The choice of Comscore as a competitor to Nielsen is accurate because both companies provide data analytics and measurement services specifically geared toward understanding media consumption and audience behavior. Comscore focuses on providing insights into audience measurement across various platforms, including TV, digital, and video, which aligns closely with Nielsen’s methodologies.

While Google Analytics, Adobe Analytics, and Facebook Insights are valuable in their respective areas, they don’t serve as direct competitors to Nielsen in the same way. Google Analytics and Adobe Analytics primarily focus on web and app analytics, tracking user interactions and behaviors within digital environments rather than comprehensive audience measurement across media. Facebook Insights serves to analyze engagement and performance specifically on Facebook and does not extend into the broader media measurement territory covered by Nielsen and Comscore. Therefore, Comscore stands out as the correct answer due to its direct competition with Nielsen in audience measurement and media insights.
