As social media are increasingly being used as a marketing platform, electronic word-of-mouth (eWOM) has also become popular in both research and business areas. However, although many studies have examined the effect of eWOM, the products investigated in most of these studies, such as films or books, are not likely to be consumed daily. Therefore, in this study, we analyze the effect of eWOM on low involvement products, which are inexpensive and enough for everyday spending. Given that low involvement products have unique characteristics such as low price, we conduct an experiment using a real sales dataset related to soft drinks. We also analyze the effect of eWOM in two social media platforms. We find that eWOM influences the sales of low involvement products, but such influence is dependent on the characteristic of the social media platform. Based on these results, we suggest that marketers and retailers selling low involvement products must consider eWOM, such as reviews, and differentiate their strategies based on their focused social media platform.

Purpose - In this study, we aimed to theorize blockchain-based social media platform users' commitment by examining the impact of their perceived justice of the token reward system. In addition, this study applied psychological ownership theory to verify the underlying mechanism between users' perceptions of justice and their commitment to the platforms. Research design, data, and methodology - To empirically test our conceptual framework in the study, we collected data through a web-based survey approach from the responses of 385 users who had experience with blockchain-based social media platforms. We employed a structural equation modeling approach to empirically test our proposed hypotheses. Result - The results indicated that distributive justice and informational justice have positive effects on user commitment. The results also showed that psychological ownership plays an important role in mediating the relationship between users' sense of distributive justice and commitment, and between procedural justice and commitment. The findings provided a better understanding of the sense of justice and user commitment in a blockchain-based social media environment. Conclusion - This study represents a preliminary attempt to theorize and empirically examine blockchain-based social media platform users' commitment. This study provided important contributions to the literature on how the effect of users' sense of justice in a reward system affects their commitment to blockchain-based social media platforms.

This research investigates how loneliness affects people's preferences for products that appear in social media ads. Four studies examine the impact of loneliness that is both measured in an established scale and situationally induced via a recall task. Individuals who experience higher levels of loneliness evaluate the same products more highly when they are advertised in a social (i.e., Instagram) compared to non-social (i.e., brand website) media platform. This effect occurs because loneliness increases people's attention to others' social evaluation of a product, and social media ads provide this information via social cues such as "likes" embedded in the ads. When the social cues are absent, the advantage of advertising on social compared to non-social media for people with high (vs. low) loneliness disappears. The findings suggest that social media ads have a unique appeal for individuals experiencing loneliness and highlight the role of social cues in shaping product evaluations.

This study examined the influence of social media on the beauty industry and analyzed beauty-related content on social media in China, Thailand, and Indonesia. The existing literature was reviewed and four social media platforms that display the active sharing of beauty-related content in the three stated countries were selected. Five information sources were then chosen from each social media platform and 115 top posts from these sources analyzed. Beauty-related material was shared on discrete social media platforms in the three countries. Differences were found in the presentation types, themes, and message strategies of the content depending on the type of product and services provided by each social media platform. The content on Xiao Hongshu in China consisted of images showcasing product specifications along with a focus on honest and detailed empirical product review messages from its general users. From Taobao Zibo, Wang Hong conveyed powerful and influential information that communicated instantly with viewers and delivered entertaining and sensory messages. In Thailand earnest reviews of beauty products were offered, along with firsthand testimonials through traditional content uploaded on YouTube. In Indonesia, beauty influencers posted creative and sensational photographs of makeup products on image-centered Instagram. This study expands the current scholarship on social media platforms and extends the scope of the extant research on beauty-related content in Asian countries. The practical implications of this study include useful indications on how beauty brands can use social media to promote their products.

So far, almost all IP media services are targeted to the specific devices, for example, IPTV services are mainly for TV, and social community services are mainly for PC etc.. This paper describes newly developed media service platform in which the high quality video services can be provided not only to the TV or PC but also to the PMP(Portable Media Player) and even to the mobile phone. The major technical issues of the service platform are synchronization of contents among the different devices and high quality TV grade video display in PMP device. We confirmed successful operation of multi-device converged services in the developed media platform. We also have a trial service plan in Gwangju city at the end of this year.

This paper proposes the presence and importance of cultural differences to address user engagement in worldwide social media platforms. Based on Hofstede's cultural dimensions, this paper addresses their new meanings in the context of user engagement in social media. Our propositions address two research questions: (1) how do cultural dimensions, displayed on social media platforms, differ across national cultures?; (2) what different preferences the social media platforms have in terms of which cultural dimensions promote or suppress user engagement? User engagement in social media platforms is explained by the cultural differences in terms of the four cultural dimensions: individualism vs. collectivism, uncertainty avoidance, power distance, and masculinity vs. femininity. Implications are also discussed for research and practice.

Purpose This study aims to investigate the factors influencing social media users' sharing behaviors of COVID-19 health information. Specifically, we seek to examine the impact of three key antecedents-trust in information source, trust in information content, and trust in social media platform-on users' trust in information quality and determine whether their effects vary between South Korea and China. Design/methodology/approach To fulfill our research objectives, we conducted an online survey across two countries, collecting 408 valid responses (South Korea: N = 201; China: N = 207) for our analysis. We employed Partial Least Squared based Structural Equation Modeling (PLS-SEM) with SmartPLS 4 and performed Exploratory Factor Analysis (EFA) and independent t-tests with SPSS 27. Findings The study revealed that perceived risks significantly inhibit users from sharing health information, highlighting the critical role of trust in countering these effects. We also identified variances in the levels of trust in information content and trust in social media platform between the two countries, which offers fresh perspectives for designing culturally tailored public health communications and interventions.
