This study explored how corporations’ CSR (corporate social responsibility) program types and media channels affect publics’ evaluations in CSR communication. The study found that types of CSR programs (corporate donation vs. interactive CSR program) are more significant than message channels (news article vs. social media) in affecting publics’ attitudes. When corporations execute an interactive CSR program that asks for consumers’ participation, publics feel more social connectedness than when corporations have a CSR program that involves a donation to the community. In addition, publics show the most favorable attitudes towards interactive CSR programs in the social media and the least favorable attitudes towards corporate donations in newspaper article. However, the study failed to find any significant results in affecting publics’ purchase intention. This study provided practical insights regarding the significance of CSR program type over media channel in CSR communication.
