Films comprise much of the content seen on most pay television services, particularly those with a general entertainment format and those that focus exclusively on films. Services often obtain rights to films through exclusive agreements with film distributors. Films acquired during the original term of license agreements with a distributor may also be broadcast as "sub-runs," in which a service holds rights to film long after the conclusion of a distribution agreement (under this arrangement, the pay service that originally licensed the rights to a particular film title, or one other than that which had held rights, may hold the broadcast rights through a library content deal).
