In a move aimed at putting pressure on DISH Network (NASDAQ:DISH), News Corp. (NASDAQ:NWSA) pulled the plug Friday on its 19 regional sports networks for viewers of the satellite television service.

The move comes as News Corp., which is also the parent of FOX Business, and DISH struggle to reach a deal on a new contract.

According to DISH, News Corp. is “demanding a new contract with an unprecedented rate increase of more than 50%.” However, a FOX spokesman called that figure “patently false.”

“DISH Network is not going to allow FOX or any programmer, to bully our customers into paying such an unconscionable price increase," Dave Shull, senior vice president of programming for DISH Network, said in a statement.

DISH, which has more than 14.3 million customers, said it plans to continue its negotiations “in good faith for a fair deal” with News Corp.

Scott Grogin, a spokesman for FOX, told FOX Business that the 50% figure is “patently false” and a “gross overstatement.” He said the two sides are not close to an agreement and that DISH waited about five months before responding to FOX’s initial offer.  

“We have attempted to negotiate with them virtually every day since then and they have not been willing to come to the table with any kind of reasonable suggestion,” said Grogin.

DISH said the talks with News Corp. don’t affect local FOX affiliates, FOX News Channel or FOX Business. While the local affiliates are not impacted by the outage, Grogin noted that  DISH’s contract for retransmission consent of local affiliates is due to expire at the end of October, meaning “that lies right on the horizon.”

In the meantime, DISH said it will make a slew of channels available to all affected customers at no additional charge, including HD Net Movies, HD Theater, NBA TV, New England Sports Network, NFL Network, ESPN Classic, FOX Sports Rocky Mountain and FOX Sports Northwest.

DISH's stock didn't appear to be hurt by the developments, rising 0.8% to $19.32 Friday. News Corp.'s shares were up 0.7% to $13.15.
