Over a year after Insight Communications launched its InsightDigital 2.0 service and threw in a trio of HD channels to boot, the cable company is now giving its loyal customers five more high-definition options along with the Digital 3.0 upgrade. Reportedly, users can now tune into Discovery, Animal Planet, The Learning Channel (TLC), TBS, National Geographic and yes, even the NFL Network in glorious HD. The Digital 3.0 package will automatically be available to digital subscribers at no extra cost, but it should be noted that Insight will raise prices in January. Additionally, the operator has nearly doubled its on-demand library and includes VOD channels for HOB, Starz, Showtime, Cinemax and The Movie Channel, but we're still left with no word on any HD VOD plans.
