摘要:A viral video is a video which gains widespread distribution through the process of Internet sharing, typically through email, blogs, and other media-sharing websites, such as YouTube. Given the popularity of YouTube with African Americans, a content analysis was conducted to examine the characteristics, content, and YouTube member responses to viral videos featuring African Americans and focusing on HIV/AIDS prevention. The top two most frequently viewed videos elicited in our search generated strong viewer comments that were grouped under three major themes: threats and insults toward the maker of the video, questions about the authenticity of the video maker’s claims, and positive comments supporting the statements made in the video. The motivation to share HIV-related videos may be related to the video’s elicitation of emotions like anger and frustration or the inspiration of feelings of encouragement or support.
