Baby Bus is fined.

In October 2025, some netizens reported that the splash screen advertisement of the well-known children's enlightenment digital content brand "Baby Bus" appeared on the edge of the video, and it was easy to accidentally enter bad pages or even automatically download unrelated software. After the incident, many parents protested, and Baby Bus Co., Ltd. apologized and promised to make improvements. According to the news from the "CCTV News" WeChat public account on March 17, 2026, for displaying vulgar advertisements that deviate from social norms in its children's apps, "Baby Bus" was fined 300,000 yuan and confiscated illegal gains of 3.68 yuan by the Cangshan District Market Supervision Administration of Fuzhou City. The report stated that on March 17, 2025, Baby Bus Co., Ltd. signed a "Mobile Advertising Alliance Membership Service Agreement" with an information technology company in Shenzhen, integrating its own mobile application advertising resources through SDK and other methods into the Mi Alliance. In the process of operating the "Baby Bus Children's Songs" app, the staff of Baby Bus failed to timely review the advertising content provided by their partners. This led to a text and image advertisement with the title "Three women serve one man, each receiving 500,000 yuan monthly living expenses, taking turns to accompany him one day a week," being directly displayed as the splash screen in the children's app. The official website of Baby Bus Co., Ltd. introduced it as a brand dedicated to creating children's enlightenment digital products, having released over 200 apps, more than 4,500 episodes of nursery rhyme animations, and over 16,000 episodes of traditional Chinese stories.
