A camcorder is a portable electronic device for recording video images and audio onto an internal storage device. The camcorder contains both a video camera and (traditionally) a videocassette recorder in one unit, hence its portmanteau name. This compares to previous technology where they would be separate. The earliest camcorders, developed by companies such as JVC, Sony, and Kodak, used analog videotape, but since the mid-1990s, camcorders recording digital video have become the norm.
