# Doctor Who: The Sixth Doctor Adventures

The Sixth Doctor Adventures is a Big Finish Productions audio play series based on the television series Doctor Who. It sees the return of Colin Baker reprising his role as the Sixth Doctor.

## History

In 1999, beginning with the story The Sirens of Time, Big Finish Productions began producing a series of audio adventures featuring the Fifth Doctor, Sixth Doctor and Seventh Doctor. For 22 years these stories continued collectively known as Big Finish's Main Range. In May 2020, Big Finish announced the main range would conclude in March 2021 and subsequently replaced with regular releases of each Doctor's adventures continuing in their own respective ranges. Several previously released special titles were retroactively reallocated into these new ranges by Big Finish.
