For each month that CBS and Dish do not reach an agreement, CBS could lose about $16 million in revenue and Dish could save about $5 million in costs, Mr. DiClemente said.

“In our view, the relatively small cost savings, along with the prospect of severe subscriber losses for Dish and forgone ad revenue for CBS, should motivate both parties to come to an agreement, minimizing the probability of an extended dispute,” he said.

The fight between CBS and Dish highlights the growing tensions between television programmers and the cable, satellite and telecom companies that distribute their programming. Television groups are battling to receive higher rates for their programming, arguing that they are spending hefty sums for costly sports rights and other programming. They also are seeking to hold on to more digital rights of their content, for their own streaming services or for selling to Internet-based outlets such as Netflix and Amazon.

At the same time, distributors are fighting to stem increasing programming costs, arguing that customers ultimately end up paying the bills. They also are seeking more flexibility in allowing customers to pick and choose the networks they want to subscribe to. Distributors also are seeking digital rights to develop their own streaming products, fearing that people will cancel their television subscriptions for cheaper streaming alternatives

“When you start having your product being available from a lot of different sources, customers don’t want to pay for it twice,” Charles Ergen, Dish’s chairman, said in a conference call last month. “Mathematically, we’re probably not going to be able to carry all the 10 major people long term and — because we just don’t want to raise prices to $100 a month, right? And so when you do that, somebody is going to drop off.”

Among the issues negotiated between CBS and Dish are digital rights, Dish’s plans for a new subscription-based streaming television service as well as its Hopper digital video recording service, which allows people to viewers to skip commercials.

CBS has encouraged its viewers via phone calls, emails and social media messages to lobby Dish to reach a deal.
