More than one million DISH Network customers across the U.S. have lost some of their TV channels.
EchoStar Communications, the parent company of the Dish Network, has pulled the plug on Viacom-owned channels like MTV, Comedy Central, VH-One and Nickelodeon.
DISH customers in 16 markets lost their local CBS affiliate programs as well. CBS will carry the NCAA basketball tournament starting next week.
DISH has posted an announcement about the cancellation on its Web site, along with a plea for consumers to call CBS.
Viacom says it has a solution. It's urging DISH Network customers to switch services.
The shutoff is the result of a contract dispute over programming fees.
