This document discusses the evolution from Web 1.0 to Web 2.0. Web 1.0 focused on one-way publication of content by businesses, while Web 2.0 enables two-way interactions and user-generated content. Key features of Web 2.0 include social networking, user-generated media like blogs and wikis, and collaborative projects. Examples show how early companies shifted to have more user-focused models as the internet transitioned to Web 2.0.
