In 1978, The ACE (Award for Cable Excellence) awards for cable programming are created. Later called CableACE Awards, the industry recognizes original programming created for cable casting. They were given from 1978 through 1997 to honor excellence in cable television as the Primetime Emmy Awards did not yet recognize cable programming. The actual trophy was a large trophy made of glass blown and cut into the shape of the Ace of Spades. In April 1998, NCTA members voted to end the ceremony as cable programming met parity with the network prime time programming being nominated for the Primetime Emmy Awards.
