The document discusses the role of public relations (PR) in events and how communication models have changed. It provides examples of how PR can measure the success of events, including media coverage generated, online activity and discussions, and stakeholder surveys. It also discusses the differences between business events aimed at return on investment versus charity events focused on feelings of goodwill. Specific case studies are provided on launches for MTV Ukraine and Profeo.com.ua to illustrate how PR strategies helped increase brand awareness, loyalty and advocacy.
