The document discusses the evolution of the web and tourism industry from Web 1.0 to 2.0. Web 1.0 referred to static, proprietary websites while Web 2.0 enables user participation through features like blogs, social networks, reviews, and user-generated content. This has transformed how companies operate and how tourists plan and provide feedback on trips through social media interactions. Tourism has similarly evolved from standardized offline offerings to individualized online experiences through Travel 2.0 applications and services.
