The document discusses the evolution of digital commerce from Web 1.0 to the current era of Web 3.0 social commerce. Web 1.0 involved static websites for companies like Pizza Hut, while Web 2.0 saw the rise of social media as a marketing channel through platforms like Facebook and Twitter. Web 3.0 now enables social and viral commerce through features like Facebook's buy button, in-stream purchases on Instagram and video checkouts, allowing purchases with just a hashtag or within videos with no extra clicks. The future is seen to involve more seamless, mobile-friendly and viral forms of social commerce.
