Where government communication in the early 20th century fell under the umbrella term, "propaganda," the post-WWII era saw a paradigm fracture into public affairs for domestic audiences, public diplomacy for foreign audiences, and psychological operations for hostile audiences. The continued diffusion of the Internet, however, has blurred such distinctions, mending this fractured paradigm. Based on in-depth interviews, this study typologizes government communication to contextualize how various tactics functions within the 21st century digital media ecology, through an "Information Intervention" taxonomy. In an age where state-sponsored disinformation and computational propaganda are tantamount threats, this paper elucidates the field's fundamental concepts by articulating who communicates with what audience, in what manner, with what intent, and with what desired outcomes.
