The document discusses the history of animation. It explains that animation works by showing still images in rapid succession, creating the illusion of movement through the persistence of vision. The timeline shows that early Philippine animation started in the 1930s-1950s with commercial purposes. Animation classes began in the 1960s and the 1970s were an experimentation stage. Outsourcing of animation to the Philippines boomed in the 1980s and the 1990s to present are considered the golden age of Philippine animation.
