The fast-moving consumer goods (FMCG) industry relies heavily on advertising to raise brand recognition, shape customer opinions, and ultimately drive sales. The function of conventional print media has changed due to the rise of digital platforms, and there is still much discussion over which is more effective. In the fast-moving consumer goods (FMCG) industry, this research compares the impact of digital and print ads on consumers' knowledge and intent to buy. To investigate demographic differences in responsiveness, trust, credibility, engagement, and memory, we used a mixed-method approach that combined primary survey data from 300 participants with secondary literature. Digital advertising has a greater impact on younger, urban, and higher-income customers' brand memory, immediacy, and impulsive purchasing, according to the data. However, when it comes to health-related and high-trust fast-moving consumer goods (FMCG), print ads still hold greater credibility and trust, especially among older and semi-urban customers. According to the research, it's not enough to use one medium; to maximise consumer effect, an integrated strategy that takes use of the best features of both channels is required.
