[en] Social media is a term referring to various activities that integrate technology, social interaction and content creation. It is fast, cheap to the consumer, easily available and part of the fabric of people’s lives. Social media also brings attention as it enables conversation that everyone can participate in. Public relations practitioners around the world have been paying attention to social media as an important communication tool. Research done in 2010 by the public relations firm Burston-arsteller found that eight of 10 Fortune Global 100 companies used at least one of the most popular social media platforms i.e. Twitter, Facebook, YouTube or corporate blogging. However, a post-Fukushima informal poll indicated many nations’ nuclear regulators are looking at broadening their social media use, although some may not know how to proceed, and everyone can benefit from the “lessons learned” by others.
