We saw a demonstration at CES 2013 and you might even be one of the test users with access to user profiles already. This summer, Netflix rolls out user profiles to everyone.
Netflix will introduce user profiles this summer
If you share your Netflix login with members of your family you probably receive pretty mixed recommendations from Netflix – especially if you have children.

This is how Netflix user profiles will appear when they arrive this summer
Netflix's solution to the problem is user profiles. Basically it means that each user has its own profile with individualized recommendations, based on the individual viewing patterns.
Netflix has experimented with user profiles for some time and some users have randomly been selected as test objects. This summer, Netflix will roll out user profiles to all users. User profiles will pop up on your smartphone, tablet, TV apps and so on. Parents will also be able to put restrictions on children’s user profiles.
