Currently, we have five televisions in our home. One of them is an old box TV that we don't use and is just taking up space. We have the big flat screen in the living room, a smart TV. Our bedroom has a smaller TV, but also a smart TV. Our 1 year old daughter has a smart TV in her room too. However, she doesn't really watch much on it as she spends her time--during the day--with me in the living room. The other smart TV is upstairs in the oldest daughter's room.
We got smart TVs for Netflix, Hulu, and all that jazz.
