Differet types of media

Definition: Printed paper that announces or advertises something publicly. Whether promoting a product, an event, or a sentiment (such as patriotism), a poster must immediately catch the attention of the passerby.

Origins: The ancestors of the poster were stone tablets on which ancient Egyptians scratched symbols. The Romans put up wooden plaques with public notices in busy squares, and in the Middle Ages poster-like notices would hang on market squares or in front of churches.

Definition: Social media are interactive technologies that facilitate the creation and sharing of content, ideas, interests, and other forms of expression through virtual communities and networks.

Origins: On one of the first true social media sites, SixDegrees.com, you could set up a profile page, create lists of connections, and send messages within networks.

Definition: Movies are a story or event recorded by a camera as a set of moving images and shown in a theater or on television; a motion picture.

Origins: The first to present projected moving pictures to a paying audience were the Lumière brothers in December 1895 in Paris, France. They used a device of their own making, the Cinématographe, which was a camera, a projector and a film printer all in one.

Definition: Television is a system for transmitting visual images and sound that are reproduced on screens, chiefly used to broadcast programs for entertainment, information, and education.

Origin: The first television shows were experimental, sporadic broadcasts viewable only within a very short range from the broadcast tower starting in the 1930s.
