Netflix said on Monday that the popular political thriller “House of Cards” will return for its third season on Feb. 27. Netflix, which tapped into new “binge” watching habits by making all episodes available at once, unveiled the new season with a silent 12-second clip of star Kevin Spacey as President Francis Underwood ascending stairs to a plane with Robin Wright, who plays his wife, Claire. “House of Cards,” the first online-only series to win an Emmy Award, also finds itself in the middle of a real-life political debate in Maryland over tax credits the show received as part of a production deal to film in the state. Maryland lawmakers say the $60.2 million in tax credits given to “House of Cards” and HBO political satire “Veep” together do not produce long-term economic gains for the state, which faces a budget shortfall next year of $600 million.
