Netflix saw a surge of 100,000 new users in the US after cracking down on password sharing. The company estimates that 100 million households are sharing passwords outside their homes. Users can now add an extra member to their account for $8 per month in the US. The move has been met with mixed reactions. Some users are willing to pay the extra fee, while others have criticised Netflix for trying to squeeze more money out of them. It remains to be seen whether Netflix's crackdown on password sharing will be a long-term success.
