Video marketing has become a central tool for brand communication as audiences move across short-form social platforms, streaming services, and traditional television. This paper examines how video format, narrative theme, and distribution channel relate to advertising effectiveness across Generation Z, Millennials, Generation X, and Baby Boomers, using The Coca-Cola Company as a case study. The source report describes a mixed-methods design comprising a structured survey of 400 respondents and four focus-group discussions involving 32 participants. It reports generational differences in platform preference, campaign recall, attention drop-off, narrative resonance, and sharing behavior. Short-form video was most prominent among Generation Z, while older cohorts showed stronger engagement with heritage-oriented campaigns. Humor received comparatively favorable ratings across all cohorts. The paper translates these reported findings into a segmented creative and media-allocation framework. The figures and statistical outputs are reproduced from the supplied project report and have not been independently verified; the results should therefore be interpreted as reported study findings rather than independently validated evidence.
