Sling TV may be one of the more expensive streaming services out there, but it’s certainly one of the best options for cord-cutters who want to ditch their cable subscription but still have a cable-esque service to watch their shows on. As a direct competitor to traditional cable companies, it’s only natural that Comcast not be too fond of it, but Sling TV’s commercials must been especially upsetting to Comcast because one of its subsidiaries, NBC, has blocked these commercials from airing on its network.
