Books and Media are forms of media that can be used in combination to share knowledge and entertainment. Books are typically published works of basic knowledge and are the oldest form of mass media. Books can be used to entertain, inform, or influence an individual or a group. Media, either through physical or digital formats, is a newer form of mass media and can be used as a primary source of information, entertainment or instruction. Examples of media include films, television, radio, newspapers, magazines, and video games. Both books and media can be used to further personal development, gain knowledge, or enjoy leisure time.
