I don't know what I would do without Netflix! It was founded in 1997 by Reed Hastings and Marc Randolph.
I know, and it has really grown.  I remember the early days when they would just send DVDs in the mail
Yes! I used to use the DVDs by mail frequently. In 2013, Netflix started making their own shows.
They really have some popular ones.  House of Cards was pretty groundbreaking.
I have never seen it. In 2007 is when Netflix started streaming as well as DVD rentals.
I know a lot of "cord cutters" who only use things like Netflix now instead of paying for cable or satellite.  It seems to be getting more and more common 
That's what I do. I use Internet television which streams cable channels instead of using a cable company.
Some of them are offering live TV like Sling TV, or Hulu.  I think it is the future of television honestly
Sling TV is actually owned by Dish network but it's great because there is no contract or cable boxes to deal with.
It is so much more convenient than signing a long term contract
