Fig. 2. Detailed breakdown of overall media consumption for Online and TV.
(A) Online consumption (including mobile and desktop) for the top 2000 sites per applications on Comscore. (B) TV consumption by program category. Total online consumption is 227 min per person per day, of which 58% is accounted for by the top 2000 sites, while total television consumption is 232 min per person per day. To compute news consumption in search and social media, excluding YouTube, we use the share of referrals from the site in question that redirect to news articles as a proxy for the share of time a user is exposed to news-related content on the platform. For YouTube, which does not redirect users to external sites, we randomly sampled 10,000 videos per month (weighted by viewing time) and computed the percentages that were classified as “news and politics”. Because portals such as MSN, Yahoo, and AOL almost always display some news-related stories on their landing pages, we count 100% of time spent on portals as news consumption. Last, news consumption in the “variety” category of television viewing is computed as 100% of time attributed to late-night comedy programs, such as The Daily Show With Trevor Noah, which are known to contain commentary on politics and current events. For clarity, (A) shows only the top 15 of 28 categories (see table S7 for numerical values).
