Daily news cycles make agenda setting and priming continuous processes

Evidence

The dissemination of television news is of course periodic, typically following cycles of 24 hours or less. The regularity and frequency of broadcasts mean that classical agenda setting and priming are, for most people, continuous processes. When news presentations develop priorities, even if rather subtle ones as in our experiments, viewers’ beliefs are affected—and affected again as new priorities arise. — John T.
