Skinny bundle service Sling TV is moving “beyond the bundle” (their phrase) by offering select streaming services and channels as standalone subscriptions and by making some on-demand content available outside of the service's paywall.Users of Sling TV's app won't have to have a paid subscription in order to access free on-demand content from TBS, HGTV, and History, among other channels. Users will also be able to purchase live pay-per-view events and on-demand movie rentals without having to have a pay TV subscription through Sling TV.The nature of the pay TV subscriptions are changing themselves, too, thanks to the new a la carte offerings. Sling TV has long offered individual premium channels and small “Extras” bundles as add-ons to the service's base packages, but now some of those channels will be available as standalone subscriptions – no base package required. The initial lineup, per Sling TV's announcement:Showtime: $10CuriosityStream: $6Stingray Karaoke: $7Dove Channel: $5Outside TV Features: $5Up Faith & Family: $5Pantaya: $6NBA League Pass: $28.99 Sling TV is positioning its move as an innovation in the skinny bundle space, but the content and pricing scheme – as well as the nature of the selection, emphasizes premium channels and subscription services rather than network channels – are reminiscent of some existing and planned services. By acting as a hub through which users can subscribe to individual channels, Sling TV will find itself competing with Amazon channels and Roku's planned channel market, among others.
