The rapid expansion of the eSports industry has attracted scholars’ attention in recent years. However, little research has investigated the evolution of the extant eSports literature. This study aimed to explore the existing knowledge base of eSports and its research networks across authors, journals, institutions, and countries by performing a bibliometric analysis. A total of 260 studies published between 2010 and 2021 were extracted from the Scopus database, which is one of the largest abstract and citation databases. Then, they were analyzed using VOSviewer. Specifically, a series of analyses were conducted: (1) citation analysis, (2) co-occurrence analysis of keywords, and (3) co-citation analysis. The findings revealed that the existing eSports literature mainly revolves around eSports games and activities closely related to eSports. Moreover, the most influential authors and publications were identified. In addition, the studies have been published in journals of various disciplines (e.g., technology and psychology), and the concepts and theories in sport-related fields (e.g., sports management) have been extensively applied in eSports research. This study’s findings contribute to a better understanding of eSports research, which can further provide directions for the sustainable development of eSports research.

For the sustainable development of the Korean Professional Baseball League (a.k.a., KBO League), it is critical to propose profitable and efficient pricing strategies for each team in the KBO League. Therefore, the purpose of this study was to understand KBO League fans’ perceptions of price sensitivity. More specifically, this study explored how fans’ perceptions of price sensitivity and latitude of price acceptance vary between different loyalty groups. A total of 213 valid responses were recruited from KBO League fans by using a convenience sampling approach. As a result, based on the levels of attitudinal loyalty and behavioral loyalty, fans were classified into four categories: loyal fans, latent fans, spurious fans, and indifferent fans. Moreover, loyal fans were found to be less sensitive to the ticket price increase of different levels (i.e., 10%, 20%, and 30%), followed by latent fans, spurious fans, and indifferent fans. Meanwhile, loyal fans have the highest level of the latitude of price acceptance, followed by latent fans, spurious fan, and indifferent fans. The findings of this study contribute to a better understanding of sport fans’ responses to the change of ticket price and their perceptions of the accepted price range. Meanwhile, this study offers practical implications for marketers of KBO League teams to develop tailored pricing strategies for their fans by considering different loyalty levels.

Objectives: We examined the mutual relationship between the Sports Promotion Act and the Enforcement Decree of the Sports Promotion Act to understand the unconstitutionality of Sport Toto in Korea. Methods/Statistical Analysis: To prove the unconstitutionality of Sports Toto, a precise understanding of its applicable Act is needed, which requires a fundamental in advance. As Sports Toto is based on the Sports Promotion Act, Article 1 of the Sports Promotion Act which the right to health, the access right to health, and the right to healthcare is based on and the chapter 4 on which Sports Toto is based on were analyzed. Findings: The results of analyzing the Sport Promotion Acts revealed that taking the social implications of Sports Toto into account, Korean people’s right to health, access right to health, and right to healthcare are infringed considerably by carrying forward Sports Toto itself. Regarding the relationship between the rationality of Sports Toto’s existence and the Constitution of the Republic of Korea in terms of unconstitutionality, various precedents related to this issue are required. Also, nothing is mentioned about people’s right to health either in Article 24~32 of the Sports Promotion Act or in Article 26~40 of the Enforcement Decree of the Sports Promotion Act which still suggests the possibility of the unconstitutionality over the relevant articles. Improvements/Applications: By diversifying and institutionalizing existing countermeasures against the social side effects, Sports Toto must take responsibility for people’s mental health, and regarding this, there is still a lot to discuss.
