ABSTRACT After the outbreak of COVID-19, people have lacked offline social opportunities and had to focus their energy on online social activities. While some researchers have proposed that both anxiety and depression have increased significantly during the COVID-19 pandemic, previous studies have provided evidence that people have mitigated negative emotions during the health crisis by using online services. In this manner, the pandemic-induced increase in online activity has significantly boosted global demand for online video services (Over-the-Top, OTT). OTT social viewing refers to the act of interacting with other users while simultaneously watching content through the social viewing service provided by OTT service providers. Drawing on the social compensation hypothesis and social capital theory, we surveyed people who experienced COVID-19-related depression and used Watch party, a key OTT social viewing service in Korea. The study reveals that while social media alone did not directly alleviate COVID-19-related depression, emotional stability was regained through building social connectedness via online activities. Furthermore, the study highlights that in OTT social viewing, the quality of interactions, rather than the quantity, was more crucial for forming social connectedness.
