Every provider every year. You know those blackouts that happened through out the year? Remember how they said they were trying to keep costs down. There was still an increase. All providers experience this annually.
Think about this- A $5 increase is an additional $65 million dollars a MONTH, $780 million a YEAR. And programming keeps getting worse. Government says there's no inflation but DISH decides it wants 5% more.
Inflation is a weighted average of many prices, so entertainment is up, but gas and many other forms of energy are cheap, so, overall, inflation is probably low. Income numbers alone tell you little about profitability but if you think Dish is raking in unusually big bucks (I don't), the company is for sale on the NASDAQ.
Keep in mind that when Dish negotiates those carriage agreements, most/all of them include annual increases for the term of the contract. That means Dish's programming cost go up each year even if no new contracts are signed that year. It isn't one channel or channel group contract that causes the annual increases, it's all of them...
