Disk Network is calling on regulators to block the pending merger between Comcast and Time Warner Cable.

As James O’Toole explained in “Dish Network wants the government to stop the Comcast-Time Warner Cable merger” on CNNMoney, if approved by the government, the $45 billion deal would result in the new company being the dominant provider of television channels and Internet connections, reaching about one in three households in the U.S.

According to a Federal Communications Commission filing, Dish, the No. 2 satellite television provider, argued the proposed merger “presents serious competitive concerns for the broadband and video marketplaces and therefore should be denied.”

In addition, it said the merged entity would be able to leverage programming content in anticompetitive ways.

O’Toole said Dish also expressed concerns over AT&T’s proposed $49 billion takeover of top satellite provider DirecTV.

If both deals go through, O’Toole said the new companies would together control close to two-thirds of the U.S. pay-TV market.

Back in 2002, he said regulators blocked a merger proposal between Dish and DirecTV.

O’Toole said Comcast dismissed Dish’s concerns about industry consolidation as self-interested.
