Mukbang is a Korean word for ‘eating livestream’. As an emerging sub-genre of internet influencers, Mukbang influencers has become the marketing tool for some firms recently. In this paper, we will conduct a case study of small sized e-commerce firms in China’s food industry. We explore firms’ perspectives towards the emerging Mukbang phenomenon, aiming to find out which factors influence the adoption of Mukbang influencer marketing by small firms. Our research results illustrate that the main point of concern for companies is the lack of information about financial data such as the average return on investment, and also the lack of information on consumer preferences and consumer analysis. Opportunity, potential benefits, uncertainty, resources available and the characteristics of the firms (or to be more specific, the management team) are important factors that influence small firms’ marketing decisions to use or not internet influencer marketing.
