Head writer

A head writer is a writer assigned with writing the majority of scripts for a television series, particularly those considered the most important to a given series.

Overview
Sometimes this can extend to, as Terry Nation did for the first series of Blake's 7, writing entire seasons of the programme. Prior to its return with a a new series in 2005, while Doctor Who did have a Script Editor, it did not had a head writer. However, in recent years, it and its spin-offs have had one.
