This document summarizes research on the use of social media by National Tourism Organizations (NTOs). The research questions examined the extent of social media use by NTOs, which platforms they use, and which platforms are used most frequently. The methodology found social media presence for 80 out of 195 NTOs (41%). Facebook, Twitter, YouTube and Flickr emerged as the most popular platforms. The conclusions note the difficulty in finding NTO websites and social media information, and that social media use does not necessarily translate to engagement.
