Sling TV is Dish Network’s $20 streaming service that delivers a couple dozen cable channels to your devices without the need for a cable subscription or contract. On just about every newspost we’ve published about Sling, we’ve lamented the lack of Viacom channels on the service. Viacom owns a mess of established cable institutions: Nickelodeon, Comedy Central, BET, Spike, MTV, MTV2, Nicktoons, Nick Jr., VH1, CMT, and TV Land, plus possibly others I can’t think of at the moment.
