Methods, systems, and machine-readable to adapt delivery of content composites to an endpoint media device are disclosed. A first content composite may be transmitted via a packet stream to an endpoint media device. A communication from the endpoint media device that is indicative of having output at least part of the first content composite for display may be processed. Operational data from that is indicative of operations executed by the endpoint media device or a communication device may be processed and mapped to one or more operational values correlated to a metric that corresponds to endpoint disconnection with the first content composite may be identified. A second content composite to be inserted into the packet stream to the endpoint media device may be selected. The second content composite may be transmitted via the packet stream from the content provider system to the endpoint media device.
