Dish is making it easier to watch video from online rival, Netflix. The satellite TV company says it is adding the Netflix app to its latest set-top boxes, its second-generation devices that were released back in February. Dish didn't say how many customers have that box. Customers with older boxes would need a replacement to use the feature. Dish customers also must subscribe to Netflix's $9-a-month service on their own - in order to use the app. TiVo also makes a device that combines regular TV channels with online video services, but Netflix said Dish is the first U.S. pay-TV provider to add the app to its own set-top box. The announcement comes as pay-TV providers, such as Dish, face challenges keeping customers who are increasingly viewing video online. It might seem odd that Dish would embrace a competitor, but the move could keep consumers using Dish's set-top box instead of switching to a stand-alone streaming device such as Roku or Apple TV. Dish plans to make watching Netflix even more seamless in the future, by adding its TV and movie titles to its search function.
