This assignment discusses the differences between Business-to-Business (B2B) and Business-to-Consumer (B2C) marketing, as well as international marketing and domestic marketing. The key points are: B2B marketing involves trade relations between business entities, while B2C marketing focuses on direct relationships with consumers. In B2B marketing, businesses need to emphasize quality aspects, whereas in B2C marketing, businesses need to focus on customer convenience. International marketing has more opportunities for competitive advantage than domestic marketing, but also faces more cultural and technological barriers.
