Korea’s largest Internet portal, Naver, launched an online donation campaign titled “Happy Energy” in 2009. It allows people to make donations easily with the click of a mouse and feel the joy of sharing with others. In order to effectively introduce the campaign, a PR film was produced. “Making a difference with a click, Happy Energy” is the main slogan stressed in the PR film. It starts with footage of the “Happy Energy” main page. With a click, a story unfolds and viewers grasp a clear understanding of the campaign’s concept and meaning. A single leaf is shown at the beginning of the film, expanding and spreading as the story progresses.
