115.9m households have TVs[1], so 23.6m accounts is just over 20% of households with TVs subscribing. That seems more reasonable. The 7% figure assumes 1 account per person.
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%.
Netflix used actually allow multiple users per account back in the day, each with their own queue. They removed that feature though, and now our household appears as one person.
Quite true. Our "recommendations" are frequently a weird hodgepodge with things like Thomas the Tank Engine and Californication right next to each other.
OTOH, this was only vaguely better when we had cable. (You could have user-specific channel lists, but it was annoying to access them. And even still, there was no way to outright remove channels from the main list - is it really necessarily for me (or my kids) to see what's currently playing on the adult channels I don't subscribe to?)
Q. Can I watch movies instantly on more than one PC or Netflix-ready device?
A. ... If you are on the Watch Instantly Unlimited plan or the 1-disc-out-at-a-time plan, you may watch only one device at a time. If you are on the 2-discs-out-at-a-time plan, you may watch on up to two devices at a time. Members on the 3-disc plan can watch on up to three devices. The maximum is four devices -- available for members on the 4-or-greater-discs-out-at-a-time plan.
Your account can have up to six unique authorized devices activated (and associated with it) at any given time, including personal computers and Netflix-ready devices. For example, if you're on the 1-disc plan, you can have up to six devices associated with your account, but you can only watch one of them at a time. If you're on the 2-disc plan, you can have up to six devices activated but can only watch two of them at the same time.
We have the 1-disc plan but routinely watch on the Wii and my desktop at the same time (but not for very long, because our bandwidth can't really keep up well; it's kind of a bone of contention here).
Wow, that's great. I couldn't find any info about it on their site for some reason, but another site[0] says it's $20/month for the 4 discs out at-a-time plan, meaning by sharing with friends and family you can defray the cost to $5/month.
