“Sling is owned by DISH. It’s basically DISH scaled down and without an actual dish.”
They are apparently cannibalising their satellite dish system as they have had the largest number of disconnects.
Charles William “Charlie” Ergen, the CEO of Dish, may be getting even with ESPN/Disney having Sling Blue without ESPN or Disney on the package. The not so great feelings between the Cable thugs and Charlie go back decades.
Several things would make it hard for me to drop DISH. For one, my wife likes to watch movies on the Hallmark channels, which do not stream. I also like TCM, which I believe is not yet on ROKU. Also, I like having the DVR. Even if I could stream those channels, I'd want to be able to DVR the programs, unless they are always on demand. I also have an OTA antenna connected to the DISH DVR and can use the DVR to record programs from OTA channels in addition to channels on DISH.
