Netflix will start canceling accounts that have been inactive for over a year, but still have an active subscription. This move is expected to affect less than half a percent of its user base, which is around 914,000 accounts. The company will send notifications to these users, asking if they want to continue their subscription, and will retain their viewing data in case they want to reactivate their account later. The decision is seen as a way to save forgetful customers money and reduce potential legal issues.
