K-Drama and K-Pop are elevating Korea’s content on the world stage, driven by fans.

The global Korean Wave fandom has grown rapidly, and domestic fandom platform markets are forming a new competitive landscape. As of 2023, the latest data from the Korea Foundation for International Cultural Exchange show about 225 million global Korean Wave fans, a figure roughly 24 times higher than in 2012.

Fans have exerted influence long before the K-Wave’s global rise, and technology has continually changed how they connect. In 1990, voicemail and telephone fan services allowed fans to leave messages and hear replies by phone; after the mobile shift, text-based private messaging became established. An early example of text-based one-to-one fan communication is UFO Town. Fans would text celebrities and receive direct replies.

SM Entertainment, which produced legendary K-Pop groups such as H.O.T, S.E.S, SHINHWA, TVXQ, and EXO, helped inaugurate much of fan culture. Today, DearU Bubble—one of the most commercialized fan-communication platforms—also originated from SM’s official fan community app Lysn, which provided community, commerce, and live features. It enabled celebrity-by-celebrity fan community boards, and the Bubble paid messaging service was added.

One of BTS’s main popularity drivers is fan communication; by making interaction a daily habit, they narrowed the distance to global fans. During the COVID-19 pandemic, encouragement messages sent via social media and content broadened influence through participatory campaigns that global fandom could join. At that time, BTS primarily used HYBE’s Weverse, a platform offering community, commerce, and live features.

Domestically, the fan platform market includes Weverse, DearU Bubble, Nomus’s From, CJ ENM’s Mnet Plus, Kakao Entertainment’s BerryZ, and Be My Friends’ BeStage. In addition, HiEnd provides services for actors such as Ji Chang-wook, Lee Jong-suk, Park Seo-joon, and Han So-hee. As the communication features of fandom platforms advance, the distance between celebrities and fans has narrowed rapidly. However, this closer proximity can generate side effects: if conversations include inappropriate content, fans can be alienated and face public backlash. Behind the evolution of fan-communication platforms lie notable challenges and problems that accompany their growth.
