The World Wide Web as the largest information source has had much progress since its beginnings. The World Wide Web (commonly known as the Web) is not synonymous of the Internet but the most prominent part of the Internet that can be defined as a techno-social system that helps human interaction and is based on technological networks. The notion of the techno-social system refers to a system that enhances human cognition, communication, and co-operation; Cognition is the necessary prerequisite to communicate and the precondition to co-operate. In other words, cooperation needs communication and communication needs cognition. This thesis provides a background of the evolution of the Web from Web 1.0 to Web 3.0. Web 1.0 as a Web of information connections, Web 2.0 as a Web of people connection and, Web 3.0 as a Web of knowledge connection. In the empirical part, the paper examines the influence of the prominence of Web 1.0, Web 2.0 and Web 3.0 philosophy in a website on consumers' attitudes toward that web site. Work will primarily be focused on the two attitude components in the context of a Web page: • Affective, expressing liking of the Website • Cognitive, expressing the perceived usefulness of the Website for users Conceived website selected research sample most applicable principles of Web 3.0, followed by the principles of 2.0, while the application of the principles of Web 1.0 comes last. The principles of Web 3.0 have the greatest impact on consumers and on components of the attitude that are included in this study, both affective and cognitive. The principles of Web 2.0 have a neutral effect, while the applying the principles of Web 1.0 in the near future would have a negative impact on the cognitive component of attitude. Regarding the principles of Web 1.0 and the affective component of attitudes, the continued application would not lead to an increase in the affective value for the user's website.
