Synthetic media, created partially or entirely through AI algorithms, has revolutionized digital marketing by enabling brands to produce personalized, scalable content without traditional production constraints. This technology allows marketers to generate hyper-realistic images, videos, and voice content that can be customized for different audience segments while maintaining consistent brand messaging across channels. As synthetic media tools become more accessible, companies are increasingly leveraging these capabilities to reduce production costs and create more engaging customer experiences, though this advancement also raises important ethical considerations regarding authenticity and potential misuse.
