How have the restrictions COVID-19 imposed on our societies around the world changed the academic public relations (PRs) and open science? The academic PR and open science partly share the mission and purposes. However, their technological backgrounds are quite different: the academic PR is based on the methods developed through the rise of mass media in the 20th century, whereas open science assumes today's matured information and communication technology (ICT). The COVID-19 pandemic imposed fundamental restrictions on these activities. Many of the academic PR activities such as events, pamphlets, and posters have been affected and replaced by internet-based online activities. Information is more accessible through universities' website and even new online communication tools have been introduced. These changes seen on their website are, though often bought up as a necessary step, an unprecedented and rapid change the COVID-19 pandemic brought in. In this study, we conduct a survey on the university websites to sketch out how the academic PR has changed in the first half of this school year (from April to September, 2020) focusing on events and student recruitment fairs, "open campus". Based on the survey data, we examine the changes in the similarities and differences between activities of open data and the academic PRs. Then, we discuss the new functionality of the academic PR and its applicability to open science in the new world after COVID-19.
