Sling TV does not currently offer HBO. WarnerMedia, HBO’s parent company, and Dish Network, Sling’s parent company, got into a carriage dispute a few years back. But stay tuned, because Dish Network and WarnerMedia recently hugged it out, corporately speaking, and now Dish Network has HBO. No word on when (or if) Sling TV might start carrying HBO, but a future deal is certainly possible.
