However, such classification scheme does not make any provision to include three significant social media types: Microblogs (e.g. Twitter and similar applications); consumer review and ratings websites (e.g. TripAdvisor and similar applications); as well as location based services (e.g. Foursquare and similar applications). For the purposes of the present study, and given holiday travel as its contextual focus, Virtual social worlds and Virtual game worlds will not be
further studied given that the literature review did not reveal any academic papers examining them in the context of travel and tourism. On the contrary, due to their impact on tourism, as evidenced in subsequent paragraphs of this chapter, Microblogs, Consumer review websites and Location Based Services are considered as additional types of social media and will be further studied.
