Netflix's password sharing crackdown boosts subscriber numbers.

Netflix's crackdown on password sharing has led to a significant increase in account sign-ups, according to data from analytics firm Antenna. The company saw the four biggest days of US sign-ups in the four and a half years it has tracked this data, with an average of 73,000 new memberships during each of the four days. While account cancellations also rose in that period, sign-ups far outpaced those figures. Netflix started cracking down on account sharing on a trial basis in Latin America before implementing the new rules in several other regions.
