As Amazon announced earlier this year, several HBO shows are now available through Amazon Prime Instant Video. Starting today, if you have an Amazon Prime account, you’ll have access to shows like “The Sopranos,” “Six Feet Under,” “The Wire,” and more. For newer shows, only early seasons are available as HBO looks to maintain its HBO Go exclusivity. Though users won’t have access to the later episodes, it gives Amazon a significant leg up over streaming video competitors Netflix.
