How Mobile Shift Fueled TikTok’s Rise: Insights from Zhang Yiming’s BEATS IN TECH Talk

At the BEATS IN TECH conference, Zhang Yiming, founder of ByteDance, delivered a talk titled “Insights, Opinions, Trends,” emphasizing that the company’s success stemmed from recognizing the shift of media from newspapers and PC websites to mobile devices.

He described ByteDance’s origins in 2012, its rapid growth to 2.9 billion activated users and nearly 30 million daily active users, and its evolution into a platform with 35,000 content creators, including media outlets, commercial brands, and government agencies.

ByteDance’s product is fundamentally a machine‑learning‑driven personalized recommendation engine, not a traditional news portal. Zhang highlighted that hiring many machine‑learning engineers and architects was essential to build this engine.

The core lesson he shared is that entrepreneurship thrives on change. He argued that the rise of mobile internet around 2009‑2011 represented a major media‑medium transformation, replacing paper with smartphones, which in turn reshaped content creation, distribution, and interaction.

He noted that this medium shift created opportunities for new platform‑type products, citing the decline of newspaper sales in Beijing’s subway and the explosive growth of smartphone shipments in 2011.

Zhang stressed the significance of efficient information distribution, describing it as a crucial production factor that can improve social, economic, and personal efficiency. He illustrated how precise, personalized recommendation can reduce regret‑type scenarios (e.g., missing a flight) and enhance overall societal welfare.

ByteDance now accomplishes three tasks: efficient distribution via its recommendation engine, fostering a vibrant creator ecosystem with millions of active accounts producing text, images, and video, and enabling rich interaction through comments, likes, and shares.

He linked the current mobile‑internet era to historical media revolutions—radio, television, and the internet—showing how each medium shift dramatically altered information flow and societal dynamics.

Looking ahead, Zhang mentioned emerging media forms such as smart watches, glasses, and voice assistants, asserting that each new medium will again reshape information dissemination.
