YouTube is a video-oriented social media platform whose popularity has increased following network technology development. Recently, there has been a rapid increase in the use of YouTube in Korea. YouTube has various contents from which viewers can choose what they wish to watch, so it is important to understand the public perception in creating YouTube content. This study aims to provide insights for content creators by identifying the popular YouTube content types using social big data technology. In addition, it analyzes public perceptions and sensibilities regarding these popular types of content using a time series model. This study explores the text posted on blogs, news, cafés, or knowledgeIN on Naver(www.naver.com) and blogs, news, and cafés on Daum(www.daum.net) over the past year to identify YouTube's latest popular content types. Frequency, network, and emotion analyses were conducted to identify the top three popular content types. The frequency analysis categorized games, movies, and music as popular YouTube content types. It was performed using three years of text data on each content type to determine the public perception. Several similar words appeared from the frequency analysis, but their rankings differed by year. The biggest change occurred in 2021 for all content types. The network analysis confirmed that the change in activation was different for each content type. Gaming density was the highest among the three content types. In addition, the degree of network activation increased significantly in proportion to the observed year. The emotional analysis showed that certain positive responses had a common high constant frequency. The most positive responses in the movie content type and the number of positive adjectives in the music content type continued to increase. This study has three implications. First, words related to content trends were identified. Accordingly, content creators can utilize the characteristics of each content type identified in this study. Second, the study confirmed the need to use social media, especially when establishing a marketing strategy for the game content type. It is more likely to have a higher marketing effect on content than the other content types. Finally, by examining the difference in the emotions experienced by the users of each content type through emotional analysis, it is possible to consider how users can maximize positive emotions when producing content. In addition, this positive response is classified into three popular factors to help manage and measure the popularity of YouTubers and YouTube content.
