Abstract: A method and system for automated media delivery to mobile devices and mobile device lockscreens. The method includes receiving a first media request associated with a first target device, obtaining a first user account associated with the first media request, wherein the first user account comprises first user category criteria; selecting a first user-submitted media item based on the first user category criteria, and sending, to the first target device, the first user-submitted media object, wherein the first user-submitted media object is presented on a lock screen of the first target device. The method further includes receiving a second media request associated with the first target device, selecting a first advertiser-submitted media object based on the first user category criteria, and sending, to the first target device, the first advertiser-submitted media object, wherein the first advertiser-submitted media object is presented on the lock screen of the first target device.
