'House of Cards': A political drama about a Congressman rising to become President of the United States: talk about a quick ascent to the top. That's just what happened to Netflix's (NFLX) stock since 'House of Cards' debuted on the video streaming service back in February 2013: a 185% increase. The show has established Netflix as a serious content producer, putting the company on the same ground as the major networks. 'House of Cards' is increasingly important to Netflix's continued prosperity, given massive subscription base of 57 million users. TheStreet's Scott Gamm reports from New York.
