The work aims to explore the path of two-way empowerment between the movie "Barbie" IP and the parent company's rebranding, and study the ways to effectively integrate the movie IP and the parent company's brand to realize two-way empowerment, with a view to shedding light on the improvement of China's movie derivatives industry and the construction of the brand. Through the comparative analysis of Barbie's brand evolution and the generalization of "Barbie's" Internet of Everything IP marketing, the overall strategy of Barbie's cross-industry cooperation and linkage was explored. Through exploring the history of the 64-year-old longevous Barbie brand's "breakage of shackles, and courage to go forward," the film emphasizes the cultural core of the Barbie IP and the emotional resonance of the audience. With the help of today's emerging social media, the old IP is more effectively promoted, and the IP licensing is extended to different areas to get success. The success of Barbie brand culture is a reference for the industry to change "their own culture into popular culture". Only through unremitting creative transformation, can brand products be recognized by the world, accepted by the majority of consumers.
