Larger interactive media tech companies use these delineations too: an animation/game company may have "line producers" whose duties are in-house active productions, while a "producer" is a former "line producer" operating as a mentor, production supervisor for multiple ongoing productions and intermediary between productions vying for the same production resources. Then the "executive producer" is the external role, creating new production pitches, presenting them to publishers/distributors/financers/IP-owners as they work to land new jobs.
