The Video Privacy Protection Act was established in 1988 to prevent video rental stores from disclosing customer records.
It also stopped Netflix from sharing viewer data with Facebook. The amendment, signed into law by President Obama in 2013, allowed rental companies to obtain customer consent to share said information with social networks. At the time, Netflix users outside the US were able to link their Facebook profiles to their Netflix profiles without any restrictions.
A Netflix spokesperson told indy100:
The privacy of our members' viewing is important to us. This information represents overall viewing trends, not the personal viewing information of specific, identified individuals.
