Introduction- The concept of online shopping was born in the late 1970s, but truly came into focus by the mid 1990s with pioneers like Amazon and eBay. Originally a transactional novelty, e-commerce has since undergone transformative changes. Web 1.0 offered basic catalogs; Web 2.0 introduced interactive user reviews and social proof; Web 3.0 and mobile apps now offer personalized recommendations, immersive experiences, and social-commerce integrations.
