EchoStar's DISH Network plans to expand its ability to deliver high-definition channels to customers this year following the launch of three new satellites this year. The company said Monday that it will be able to offer 100 national channels in HD, up from the current 76, and add numerous local HD channels in some 100 markets, up from the current 65. Customers who sign up for the HD packages, which start at $10 per month for a package of 20 channels, will receive a free ViP722 HD digital-video recorder, three months' free programming, waived activation fees and nine free months of its DISH Home Protection Plan.
