INDIANAPOLIS — Comcast has recently sent notices to its customers informing them that the company will make several changes to its programming lineup in systems that were acquired from Insight on Jan. 1. The changes are expected occur in early May.

Among the changes, Comcast is adding 13 new HDTV networks to its lineup. Popular networks like ABC Family, Disney Channel, Animal Planet, Nickelodeon, A&E, AMC, HGTV, Food Network, and CNN will be available to all of Comcast’s HDTV customers at no additional charge. Customers who subscribe to the premium movie network Starz will also get that network in high definition. Comcast charges $7 per month for an HDTV converter.

“Comcast will continue to make HDTV a priority in 2008,” said Mark Apple, Comcast regional vice president of public relations. “In addition to launching these linear HDTV networks, we are also making more HD content available On Demand. By the end of the year, Comcast customers will have access to more than 1,000 HDTV choices every month. More people already get HDTV service from Comcast than from both satellite companies combined, and Comcast will continue to be the HDTV leader into the future.”

Comcast is also making more networks available to its Digital Cable customers, with the addition of Fox Reality and Fox Business Network to the Digital Classic lineup.

Comcast will also launch a Sports & Entertainment Package, which will feature several networks, most of them new, including NHL Network, Fox Soccer Channel, GOL TV, Tennis Channel, Outdoor Channel, Sportsman Channel, and NBA TV.

The company also announced that a few networks will no longer be offered. ESPN-U, Lifetime Real Women, American Life and I-Life will no longer be available because Comcast does not have a programming contract that allows the company to offer those networks.
