I was more reflecting on newspapers not being mentioned at all as a news source. ABC World News Tonight, This Week, and Frontline are all TV sources, and Time Magazine is a pretty different beast. Back in the day newspapers and radio were pretty significant news sources for people (and radio still is).
I don't know if I'd call newspapers long form, as they certainly have lots of short articles, but I'd say they regularly have "longer form" than Frontline.
Certainly a fair number of people got daily newspapers at one point. Post-uni, I never actually lived especially near a city and never felt the need to subscribe to the (in my case) Boston Globe which wasn't especially relevant to my day-to-day life. (To this day I don't although I do subscribe digitally to the NYT and the Economist.)
While there are/were Sunday magazines, I'd generally consider magazines more broadly for deep dives into particular aspects of culture, politics, and hobbies.
