The US Census Bureau projects that last year's census will count 114.8 households in America.[1] That tracks pretty closely to what Nielsen has measured. So you don't really need the "with TV's" qualifier. It appears nearly every American house has one.
What is interesting is that I know a lot of people who share Netflix accounts across households. I wouldn't be surprised if the percentage of Americans who use Netflix is closer to 25%.
