Public relations involves establishing mutual understanding between an organization and the public through planned efforts. It aims to connect with the public to achieve organizational objectives and influence public opinion. Some key PR tools include press releases, interviews, corporate films, company magazines, sponsorships, donations, and social media presence. Sponsoring events allows companies to connect with target audiences while gaining branding opportunities. Companies must carefully select, design, execute, and evaluate sponsorships and organized events to achieve their objectives. Ambush marketing involves competing companies deflecting attention from official sponsors of an event.
