Today, Viacom and Amazon announced their multi-year agreement to stream Viacom TV shows exclusively on Amazon’s Prime Instant Video service. Viacom is one of the largest media conglomerates in the world, comprised of a large number of TV networks including MTV, BET, Nickelodeon, and Comedy Central. The agreement also comes at Netflix’s expense whose own agreement with Viacom recently expired.

It’s a huge blow for Netflix subscribers, as shows broadcast on any of the aforementioned networks (like South ParkRocko’s Modern LifeWorkaholics, Teen Mom, etc.) will be unavailable to them. At the same time, it’s a huge gain for Amazon, as Prime Instant Video hasn’t had access to worthwhile content. Does this mean Netflix, who’s experienced a bit of a subscription bump with exclusive series like Arrested Development premiering, will lose a large number of its 20-something demographic with this huge exodus of shows? We’ll see. I know one thing: I finally have a good reason to actually use my Prime Instant Video subscription.
