Customer churn
Customer churn refers to when a customer (player, subscriber, user, etc.) ceases his or her relationship with a company. Online businesses typically treat a customer as churned once a particular amount of time has elapsed since the customer's last interaction with the site or service.
Sky customer services uses a newer and far more accurate approach to customer churn prediction: at the core of Sky’s ability to accurately predict which customers will churn is a unique method of calculating customer lifetime value for each and every customer. - http://qwikfix.co.uk/sky-customer-services/
