Traditional marketing was mostly offline but expanded online when the Internet and technology became more
available.
Businesses discovered that these new tools could find out who their customers were, provide them with what they needed, and develop loyalty to their brand.

Social media created “influencers” who could use their platforms to engage with potential customers and communities.

preferences and optimize their marketing efforts.
