Todd Spangler NY Digital Editor At least initially, Netflix’s broad password crackdown appears to be producing the streamer’s desired results in converting freeloaders into paying customers in the U.S., according to early data from research company Antenna. On May 23, Netflix began notifying U.S. customers that users on their accounts who live outside their households would need to be added as an “extra member” (or get their own subscriptions). Since then, Netflix has had the four single largest days of U.S. user sign-ups since January 2019, when Antenna first began tracking the metric. Based on the most current Antenna data available, Netflix saw average daily sign-ups reached 73,000 from May 25-28, a 102% increase from the prior 60-day average. That was more than the spikes in subscriber sign-ups Antenna recorded during the initial U.S. COVID-19 lockdowns in March and April 2020.
