Using social media, especially Twitter, RNIB deliberately changed their brand perception from an organization focused only on blindness to one that provides a wide range of services. They created a Twitter marathon with the hashtag #RNIBinaday to shed light on these various services. The marathon reached over 100,000 people and received very positive feedback, with many people saying they learned something new about RNIB. Other companies like Kia UK and Nestle have also effectively used Twitter to change their brand perception in a positive way.
