Associate producer

An associate producer is a high ranking member of the production staff who is generally subordinate only to the producer and executive producer, but who also has a set of responsibilities defined by the producer or one of the execs.

In the classic era, the title, associate producer was used for only two people: Mervyn Pinfield (from An Unearthly Child to The Romans and again for The Daleks' Master Plan) and Peter Bryant (for The Faceless Ones and The Evil of the Daleks).

The title is much more common on in the BBC Wales era.
