Edward Erasmus gave a lecture on online marketing and social media. He defined social media as online platforms where users can interact and share information. He explained that social media marketing is promoting businesses through social media channels. The key reasons to consider social media marketing are the engagement and word-of-mouth it facilitates from user interactions, and that the emerging Generation Y is tech-savvy and influenced by peers online. He outlined how to get started with social media marketing through defining objectives, audiences, strategies and choosing appropriate channels.
