Dispersal of COVID-19 related information from YouTube plays a vital role in containing the pandemic and diminishes associated anxiety in the population. This study investigated the characteristics of popular YouTube videos related to COVID-19 outbreak. YouTube videos were searched using the COVID-19 related specific keywords with the eligibility of at least 1 million views. The videos were classified as types of videos (News, TV Shows, Educational, and Documentary) and sentiment-based titled videos (Positive and Negative). Total viewership, length of videos, comments, likes, subscribers of the channel, and the number of days since upload was recorded as video and user engagement characteristics. A total of 93 videos were found eligible to include in the study. About 44.1% of videos were educational and 32.3% of videos were news updates related to COVID-19. Furthermore, 45.7% of videos had a positive sentiment-based title whereas 53.2% of videos had a negative sentiment-based title. Viewer's comment responses were classified into nine various categories; most frequent comments were sarcastic/humorous (21.5%) category. Results revealed the differences in audience behavior in response to different types of videos and sentiment-based titled videos. YouTube has a significant amount of informative COVID-19 videos and incorporating certain characteristics can increase YouTube video popularity.
