Sony isn't getting specific about a particular date when HBO will officially become available on Vue; the company is only promising to have it up and running before Westworld's premiere on October 2nd. The launch of HBO and Cinemax on PlayStation Vue will mark the first time HBO’s live programming and Cinemax’s channel will be available directly to you as standalone channel offerings," Sony's
blog post reads. "That means through PlayStation Vue, you’ll have the option to subscribe to HBO and Cinemax as standalone channels or add them to your existing PlayStation Vue plan." Rival internet TV service Sling TV also offers HBO for $15 extra each month, but it cannot be purchased standalone.
