Influencers are individuals or organizations with a significant number of audience on social media. Currently, influencer marketing has emerged to be one of the most powerful marketing tools in the global e-commerce market with its market size reaching 2 billion U.S. dollars as of 2017 with an estimated market size of 50~100 billion U.S. dollars by 2020 (source: Kotra, Korea Trade-Investment Promotion Agency, ).
