If you’re a DISH Network customer, expect to start seeing a teensy $1 credit on your monthly bill. But don’t expect to be seeing MTV, BET, Nickelodeon, VH-1, or a host of other Viacom channels. When the clock struck 12 last night, DISH dropped ’em all after the two companies failed to reach an agreement on transmission-rights fees. CBS was also on the chopping block in 16 major cities, including Los Angeles and New York. Life without Two and a Half Men? The horror, the horror. That monthly dollar is going straight into my liquor fund.
