Comcast, the Richmond, Virginia-area cable and internet provider, has dropped ShopNBC and five other networks from its basic service line-up in order to meet customer requests for additional services.  (Because one analog channel consumes the same amount of bandwidth as 10 digital channels or 3 HD channels, the lineup change will allow the company to free up bandwith for other uses.)  More than 60 percent of Comcast customers in Indiana have digital cable and will not be affected by the switch.  Those who are affected can take advantage of Comcast’s offer of a free digital box for a year so they can get digital programming. Thereafter, the cost of the box will be $1.99 per month.  Palladium-Item (IN) Sept. 17, 2008
