The novel Coronavirus disease 2019 (COVID-19) is unprecedentedly changing the world since its outbreak in late 2019. Using the collected the data related to COVID-19 and the social media user data from a mobile application market research agency from January 25 to April 7, this study empirically examines the effect of the number of confirmed COVID-19 cases worldwide, the number news COVID-19, and the enforcement of social distancing measures on the daily active users (DAU) of two social media services - Twitter and Facebook - in South Korea. There are three important findings from the results of econometric analysis. First, the number of confirmed COVID-19 cases worldwide has a negative effect on the DAU of social media. Second, the number of COVID-19 news is negatively associated with the DAU of social media. Finally, the implementation of social distancing measures has no significant effect on the DAU of the social media. Theoretical implications and managerial guidelines are also discussed.

The mobile game market is fast growing after the Kakao game launched. Especially, the market is placed at the second highest by occupying 33.1% of the market. However, the rate of the total sales amount is only 6%, showing quite an imbalance between the market occupancy and the sales amount. This means that the profit-making models are not stabilized yet in the mobile game market. The absence of profit-making models can be ascertained by the relationship of DAU and sales ranking. There are several games which are ranked at DAU Top10 among Google free games, but not ranked at top 10 among sales amounts. On the other hand, there are several games which are low in DAU ranking but high in sales amount ranking. This result shows that there is no direct interrelation between the product attractiveness which users feel and the profit-making models in the market. This study compared the Google play free games which are ranked at top 10 in terms of DAU ranking and sales amount ranking to find out the factor which causes the imbalance between the DAU ranking and sales amount ranking. Based on this outcome, this study presents the reference point for the design of profit-making models on behalf of the manufacturers who wish to launch into the mobile game market in the future.

콘솔 및 PC 게임이 모바일 플랫폼으로 진출하는 경우 기존에 출시했던 플랫폼과 다르게 모바일 플랫폼에 맞는 조작, UI, 과금 정책 등의 다양한 부분을 고려할 필요가 있다. 모바일 플랫폼의 화면 크기 조작의 한계를 반영해 전투, 퀘스트 진행, 파티 조합, 장비 장착, 캐릭터 육성 등 게임 플레이 전반의 자동 시스템을 구축해 유저에게 조작 편의성을 제공할 필요가 있다. 또한 기존의 유료화 게임 형태의 판매 전략에서 부분 유료화의 전환에 따른 기존의 유저가 느낄 수 있는 과금 거부감을 해소하기 위해 시즌 패스, 월정액 시스템 등을 도입해 소 과금으로 유저들에게 게임 내에서 만족감을 느낄 수 있도록 하는 것이 중요하다. 본 논문에서는 게임의 일회적인 판매량이 매출에 영향을 주는 것과 다르게 주기적인 유저들의 접속(DAU, MAU)에 따른 과금 정도가 매출 및 게임 순위 등에 영향을 주게 된다. 따라서 꾸준한 업데이트와 이벤트 제공을 통해 기존 유저들이 장기적으로 게임에 접속하도록 유도하고, 신규 유저들이 게임에 유입될 수 있도록 하는 과정과 같은 발전 방안을 제시해 본다.
