Unlike Dish Network LLC (Nasdaq: DISH), Sony is going after the higher end of the pay-TV market. Right now it’s missing critical content from the Walt Disney Co. (NYSE: DIS)-owned networks (including ABC and ESPN), and Sony will likely have to correct that flaw if it’s going to compete with cable companies. Performance may also be an issue. If there’s too much buffering, for example, customers will have a hard time swallowing the hefty monthly fee.
