Amazon announced today that they will now have content from Viacom on their Amazon Prime streaming service.

This comes just a day after we reported on an announcement from Redbox and Verizon about their new streaming service, and about how competition between streaming services is ramping way up.

Last October Amazon added Disney/ABC content to it’s Amazon Prime streaming service, bringing the total number of shows and movies available in its library to about 13,000. With the addition of Viacom content, Amazon Prime now has about 15,000 shows and movies available.

With the Viacom agreement, Amazon Prime will gain shows from MTV, Comedy Central, Nickelodeon, and BET. Some of the individual shows that Amazon specifically mentioned adding include Avatar: The Last Airbender, Dora the Explorer, iCarly, Yo Gabba Gabba, Chappelle’s Show, The Sarah Silverman Program, Strangers with Candy, Hot in Cleveland, several past seasons of The Real World, Basketball Wives, and Jersey Shore.

Amazon Prime costs $79 a year and includes the ‘Instant Video’ streaming content, free two day shipping on many Amazon products, and access to the Kindle Owners’ Lending Library.

Last month, the CEO of Netflix warned his shareholders that Amazon may come out with its own standalone streaming service at less than Netflix’s current $8/month price. If Amazon does come out with a standalone service, this added content from Viacom would certainly add value to it.
