Further bolstering its "Watch Instantly" library, Netflix on Friday expanded its licensing deal with NBC Universal to stream shows like "Saturday Night Live," "30 Rock," and "Battlestar Galactica."

The multi-year deal kicks off next week, bringing the NBC content to Netflix's streaming library for the first time.

Among the shows being added to "Watch Instantly" is "Saturday Night Live." Netflix will add episodes from every season of the show's 35-year run, as well as day-after broadcasts for the upcoming 2010, 2011, and 2012 seasons.

NBC will also hand over every episode from last season's "30 Rock," "The Office," and "Law & Order: SVU," as well as episodes from earlier seasons. Netflix will also add all seasons of "Friday Night Lights."

From NBC Universal's cable channels, Netflix will also get USA Network's "Psych," "In Plain Sight," and "Monk." The service will also add 75 episodes of Syfy's "Battlestar Galactica," as well as the series "Destination Truth" and "Eureka."

"This agreement adds meaningfully to the wide variety of content that can be streamed from Netflix and breaks new ground in our relationship with NBC Universal," Ted Sarandos, chief content officer for Netflix, said in a statement.

The news comes as Jeff Zucker, chief executive of NBC Universal, announced Friday that he would step down from his position after NBC's merger with Comcast is done.

Though "Watch Instantly" does not include all movies available via the Netflix's DVD service, the company has been bolstering its library with several recent licensing deals, including Nu Image/Millennium Films, Epix, and Relativity Media.

On Thursday, Neflix chief executive Reed Hastings said the company was thinking about offering a streaming-only service in the U.S. Netflix expanded its business into Canada this week, where it is offering a $7.99 per month streaming-only service.
