This study examines online social media diffusion across different countries that will help to provide a picture of current global online social network services (SNSs). Analyzing country-level data drawn from 78 nations, we find that non-technological factors such as culture and language as well as technological factors including Internet penetration rate and smartphone adoption rate have significant effects on online social media diffusion. These findings, derived from a broad range of different countries, not only provide theoretical insights into understanding critical factors that enable successful global expansion of online social media services but also help practitioners plan their marketing strategies more effectively in a global context.

Although cloud computing is considered a paradigm shift of IT service design and delivery and intrigues large amounts of interest from business entities, few studies have examined the business performance of this new IT practice. To better understand the value-creating feature of cloud computing, this study aims to investigate economic payoff from cloud computing investment. Employing the event study methodology, we analyze 219 firm-level announcements regarding cloud computing initiative. The results indicate that cloud computing adoption announcements can increase the market value of announcing firms in terms of abnormal stock return. In addition, we identified differences in the effect of cloud computing adoption on market returns according to contextual factors such as strategic adoption intention, firm size, and industry sector. These results can be used as useful references for firms’ decision-making about whether to adopt cloud computing to maximize their business values.

In Twitter, a user can post a message below 140 characters on his/her account, and can also repost a message of other users who the user follows. The message posted by the user in turn can be seen and reposted by other users who follow the user, which is called Re-tweet (RT). While some messages spread widely, other messages have relatively less or no RT. What factors cause these quantity variances of RT originated from original messages? How can the messages become influential in online social networks? As an effort to answer the above questions, we focused on information vividness, message characteristics, and originator characteristics. In perspective of managerial implication, we expect that the findings of this paper will provide corporations with helpful insight on the Word-of-Mouth (WOM) effect for efficient and effective advertisements and communications when they send a message of new products or services through Social Network Services. In perspective of academic implication, we identify the effect of contents of a message on WOM, which has been dealt with by few social network researches.

In this paper, we explore the information diffusion mechanism under social network environments by investigating the effect of message characteristics on the volume and speed of retweeting in Twitter, a popular online social media service. To this end, we select eight main keywords (i.e., ‘무상급식’, ‘반값등록금’, ‘나가수’, ‘평창’, ‘김연아’, ‘박태환’, ‘아이폰’, ‘갤럭시’) that have been popular on online social media in recent days. Each keyword represents various social aspects of Korea that recently grab people’s attention such as political issues, entertainment, sports celebrities, and the latest digital products, and eventually holds distinctive message characteristics. Analyzing the frequency and velocity of retweeting for each keyword, we find that more than half of the sample messages posted on Twitter contain personal opinions for the certain keyword, but we also find that the tweets which include objective messages with hyperlink are the fastest ones when being retweeted by other followers. In overall, when being retweeted, the group of messages related to the certain keyword present distinctive diffusion patterns and speed according to message characteristics. From academic perspective, the findings in the study broaden our theoretical knowledge of information diffusion mechanism over online social media. For practitioners, the results also provide managerial implications regarding how to strategically utilize online social media for marketing communications with customers.

In recent years, IT advancement has brought out the new Internet communication environment such as online social network services, where people are connected in global network without temporal and spatial limitation. The popular use of online social network helps people share their experience and preference for specific products and services, thus holding large potential to significantly affect firms’ business performance through Word?of?Mouth (WOM). This study examines the role of online social network in raising WOM effect on the movie industry by comparing with the similar role of Internet portal, another major online communication channel. Analyzing 109 movies and data from both Twitter and Naver movie, we found that significant WOM effect exists simultaneously in both Twitter and Naver movie. However, we also found that different figures of online viral effects exist depending on the popularity of movies. In the hit movie group, before the movie release, the WOM effect occurs only in Twitter while the WOM effect arises in both Twitter and Naver movie at the same time after the movie release. In the less-popular (or niche) movie group, the WOM effect occurs in both Twitter and Naver movie only before the movie release. Our findings not only deepen theoretical insights into different roles of the two online communication channels in provoking the WOM effect on entertainment products but also provide practitioners with incentive to utilize SNS as strategic marketing platform to enhance their brand reputations.

Due to the government"s policy of vitalizing credit card use, it has become the most common payment method in Korea. Daily use of credit card and related information technologies raise the importance of protecting personal information. However, there happened a huge leakage of about 100 million personal information from three major Korean credit card companies in 2014. Despite such a serious information security accident, the “Take No Action” paradox, which does not comply with the privacy rules based on reasonable and rational judgment, is still prevalent. This study examines how consumers’ emotion toward privacy affects their information protection behavior. We also compare the effects of cognitive evaluation and rational calculation on behavioral intention and actual behavior. The results show that consumer"s emotional and cognitive evaluation had a significant effect on their personal information protection behavior. This study contributes to extant literature by considering consumers’ emotional aspect of information security and empirically examining its effect on information protection behavior. This study also provides theoretical and practical implications by comparing and analyzing protection behavior between people who experienced personal information leakage and those who did not.

Big data has been recently recognized as a strategic tool to enhance firms’ competitiveness and one of the growth engines that create new knowledge industries. Accordingly, domestic and global market of big data is expected to grow in a rapid pace. Firms are also trying to figure out how to effectively use big data for their market competence. Despite the positive market expectations and firms’ growing interest, there has been a paucity of empirical studies on the use of big data in corporate environment. To bridge such gap, this study conducts a case study regarding an integrated customer log system at a Korean home shopping firm. For the case, the study explores the business backgrounds of introducing the system, its technical features, implementation procedure, benefits and practical implications. Our study contributes to IS research by expanding existing literature to empirical analysis for the corporate use of big data and can be used as a reference to understand the direction of implementing and utilizing big data system for strategic purposes.
