Netflix is adding yet more content to its streaming offering. This time, the company’s existing partnership with Viacom and MTV Networks is getting an expansion that sees more episodes of popular television shows coming to Netflix’s on-demand service, effective immediately.

That means subscribers now have access to episodes of Yo Gabba Gabba, more episodes of Spongebob SquarePants, True Jackson VP, iCarly, and Dora the Explorer from Nickelodeon, so the children have more things to watch on Netflix.

The content expansion also includes new episodes of MTV’s Jersey Shore and The Hills, as well as episodes of The Buried Life and The City. It also has new shows from BET like American Gangster, and more Comedy Central content like episodes of The Sarah Silverman Program. There is also some amount of unspecified content form VH1, Logo, and Spike.

“We’re pleased to be able to offer programs to suit different ages and tastes and, as always, remain committed to bringing you more great TV shows and movies to watch instantly when and where you prefer,” wrote Netflix VP Content Acquisition Cindy Holland on the Netflix Blog.

Netflix is rapidly expanding its streaming on-demand offerings. Last week, the company announced a multi-year deal with Miramax, which will see the addition of a whole bunch of movies, which when combined, account for 284 Academy Award nominations.

In addition to expanding upon its content offerings, Netflix has also continued to expand upon the number of devices it supports. Recently, the company announced a new Android app that works for some Android devices, and said that they were developing for additional Android devices. As Google’s mobile platform continues to gain market share of its own, compatibility here will be key for continued Netflix growth, especially considering that Google is now renting movies directly from the Android Market and YouTube.
