NEW YORK ( TheStreet) -- Netflix ( NFLX) is making an aggressive push to ramp up its television streaming content. This week the company said via its blog that it is adding series from NBC Universal, including new seasons of The Office and 30 Rock and the first two seasons of Parenthood. Cindy Holland, vice president of content acquisition, posted: "These shows are part of a huge assortment of entertainment we now have available to watch instantly in the U.S. from NBC Universal ... In the coming weeks, there will be plenty more great series available to watch instantly as well, so keep checking it out." Netflix has also made The Wonder Years available for streaming. This comes as Netflix attempts to woo back subscribers following several strategic blunders, including the recent price hike and split-up of its DVD-by-mail and streaming services. -- Written by Jeanine Poggi >To contact the writer of this article, click here: Jeanine Poggi. >To follow the writer on Twitter, go to http://twitter.com/jpoggi. >To submit a news tip, send an email to: firstname.lastname@example.org.
