Web 2.0 is related with web applications that enable users to share information online, as well as Videos and pictures. Before the Web 2.0 came about being there was the Web 1.0. When comparing Web 1.0 to Web 2.0 we can immediately see what huge improvements have been made for users. For example, the Web 2.0 now provides the user with more user-interface as well as more storage and software facilities through their browser.
While Web 2.0 is making it easier and faster to upload and share information it has also helped the tourism industry in many ways. One of these would be E-WOM, which refers to how people communicate their experiences with each other on the web, therefore, when we talk about the decision making process to do with the purchasing of a product or service this may be the most influential factor that contributes whether a customer will purchase the service or not. While the customer is going through the decision making process whether or not to buy a service or product he may come across some "E-WOM" which will have an impact on his decision; depending if the word of mouth was positively or negatively related to the service or product .
