Micro-blogging, especially Twitter, has become widely used by media and PR in Western Europe and the US to monitor trends, engage stakeholders, and respond quickly to events. While initially just used for status updates, Twitter is now a critical tool for tracking topics and conversations. Mainstream media also uses Twitter as a source for stories and many have launched Twitter channels, though full integration into other online activities is still limited. The future of communications on social media platforms like Twitter will focus on speed, visual content, and global, responsive engagement across devices.
