The history of multimedia began with the combination of different mediums like text, images, sound and movement in television and films. Early examples included the 1972 video game Pong and developments in computer graphics and interfaces in the 1970s and 1980s helped drive the computer revolution. Key companies and software like Apple, Microsoft, Commodore, and Macromedia's Director and Flash helped establish and advance multimedia capabilities and make interactive multimedia presentations and online content possible. Multimedia has continued to evolve and improve each year.
