NEW YORK--(BUSINESS WIRE)--In typical Adult Swim fashion, the network again steered clear of the norm and provided to a packed house of 500 television media buyers, executives and press an Upfront presentation like no other. Basic cable’s leading network with Adults 18-34 partnered with Microsoft’s Zune to unveil its new fall line-up on specially-branded Zune digital media players. Event attendees enjoyed a festive Adult Swim party earlier this evening in New York, complete with food, drink and Adult Swim series activities. Instead of sitting through a presentation filled with numerous charts, video clips and lectures, guests were surprised to receive their very own presentation in hand at the end of the night—on their new Zunes. The 30 gigabyte Zune players were pre-loaded with a video presentation hosted by the dapper film aficionado and columnist from Turner Classic Movies, Robert Osborne, and also included full episodes from new and returning series, original music and still photos.

“Adult Swim’s mission is to challenge the status quo, offering edgy, hilarious, often in-your-face programming that gets noticed,” said John O’Hara, senior vice president and general sales manager for Adult Swim. “So we are pleased to partner with Microsoft’s Zune to deliver our new line-up on a sleek, cutting-edge device that will definitely get some attention—and provide our guests a great form of entertainment.”
