City branding aims to promote a city through marketing activities to alter external perceptions and encourage tourism, residents to move in, and businesses to relocate. It can be achieved by developing landmarks, nonprofit marketing, creating a strong identity, innovative services, and investments. The goal is to attract more tourists, investments, promote alternative places and sights, change negative perceptions, and create long-term prosperity by encouraging activities. Successful aspects to promote include entertainment, arts, and mega events, as demonstrated by campaigns for Athens, New York, Melbourne, and Amsterdam.
