According to recent research, what medium is the most effective for acquisition of political information?

The most effective medium for the acquisition of political information is television news.

Explanation:

By-Product Theory is the idea that many Americans acquire political information unintentionally rather than by seeking it out. This makes media like television important because television reporters relate both the facts and their analysis of political issues and the politicians who work at the local, state, and national levels. There is however an emerging age difference in how Americans source their news; Older Americans are more likely to read newspapers and watch the TV networks for political commentary and current events, whereas younger Americans tend to use the Internet to find their political information and to research candidate platforms and candidate history.
