When they first started, people came for The Office or Scrubs. Then they started creating their own, and every new show huge press. House of Cards, Orange Is The New Black, etc. But as they add tons more content, they need more traditional ways to get people interested.
People have a "no ads!" stance and forget the way they got into most shows they like are ads. As they make more content themselves (as opposed to The Office or Arrested Development), they need more steady ways to get people interested.
