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.
