(Reuters) – Venture Capital firm Andreessen Horowitz is investing $50 million in BuzzFeed, the social news and entertainment website known for producing advertising-sponsored listicles that go viral. Chris Dixon, a general partner at the venture capital firm, said in a blog post that he would be joining BuzzFeeds board. His arrival comes three months after Jon Steinberg said he would step down as president and chief operating officer. Founded in 2006, BuzzFeed is among the top 10 most-visited news and information sites in the United States, joining the ranks of long-established media outlets such as CNN and the New York Times.
