The document discusses how social media was used to rescue Iceland's tourism industry after a volcanic eruption in 2010 negatively impacted visitor numbers. Travel to Iceland was predicted to decrease by 30% and cost £180 million in lost revenue. To address this, Iceland used social media platforms like Facebook, Twitter, and video to tell personal stories from visitors and change negative perceptions of Iceland as a tourist destination. This social media campaign increased actual visitors by 79,252 above forecasts, resulted in total revenue of £138.7 million, and improved perceptions of Iceland in its three main tourist markets by 48%, 25%, and 24% respectively. The campaign demonstrated that mass social participation and personal stories on social media can boost tourism.
