ATLANTA, April 2, 2013 /PRNewswire/ -- GMC TV, America's leading television destination for "Uplifting Entertainment," unveiled today its most ambitious upfront original programming slate in the network's eight-year history. GMC TV, the fastest-growing entertainment network in ad-supported cable, up 80% among W25-54 (source 1), is presenting dynamic 2013-2014 opportunities to advertisers during the upfront, across a slate of 66 originals, including GMC World Premiere Movies, GMC World Premiere Series and GMC World Premiere Stage Plays. The upfront presentations are held on GMC TV's Upfront Tour Bus, which serves as the network's mobile venue for client meetings and events. In addition, the network said it is accelerating the timetable for its recently announced name change to UP, the latest stage in the channel's evolution as America's leading television destination for "Uplifting Entertainment." The changeover will occur on June 1 instead of September 1 because of overwhelmingly enthusiastic response by advertisers, distributors and the general viewing public. The fresh, new brand initiative is designed to communicate a clear sense of the network's unique brand position, which has always been, and will continue to be, "Uplifting Entertainment." "The response to our rebrand has been phenomenally positive," said Charley Humbard, president and CEO, GMC TV. "The beauty of UP is that it needs no explanation. It captures the essence of our brand – uplifting entertainment - and will lend itself to many interesting and fun creative executions both on-air and in print. This is a tremendously exciting milestone in the history of our network." The network enters the 2013-14 upfront season with significant ratings momentum. In addition to being the fastest-growing entertainment network in ad-supported cable in 2012 among W25-54 (+80% growth), GMC in 2012 was the second fastest growing among A25-54 (+67%), A18-49 (+50%) and W18-49 (+62%) (source 2).
