The Primetime Emmy Awards, or Primetime Emmys, are part of the extensive range of Emmy Awards for artistic and technical merit for the American television industry. Bestowed by the Academy of Television Arts & Sciences (ATAS), the Primetime Emmys are presented in recognition of excellence in American primetime television programming. The award categories are divided into three classes: the regular Primetime Emmy Awards, the Primetime Creative Arts Emmy Awards to honor technical and other similar behind-the-scenes achievements, and the Primetime Engineering Emmy Awards for recognizing significant contributions to the engineering and technological aspects of television. First given out in 1949, the award was originally referred to as simply the "Emmy Award" until the International Emmy Award and the Daytime Emmy Award were created in the early 1970s to expand the Emmy to other sectors of the television industry.
