Apple has just added the Showtime Anytime channel to Apple TV, following its reintroduction of the iTunes Festival channel. The new channel is basically Showtime’s version of HBO Go — it’s been available on the App Store for some time. Showtime Anytime has on-demand content and live streams of Showtime East and Showtime West for authenticated TV subscribers. Some free full episodes of Showtime shows are even available without cable or satellite authentication. Interestingly, the channel’s name may scroll from right to left when it’s selected, as there are too many characters to fit all at once with the 720p version of the Apple TV. No scrolling is evident on later 1080p Apple TV models.
