Having seen Sling advertised elsewhere, I wasn't even sure it was a Dish product.
So, did Dish develop it or buy it? If they bought it, why didn't/doesn't Murdoch go after the source?
Sling was originally a company that made peripherals that could work with any set top box. Echostar saw this and liked what they saw so they bought out Sling.
Sling still sells there own hardware that works with any provider, Dish just bought the company so that they could put there own spin on the tech lol.
