Doctor Who

Doctor Who is a British science fiction television series which was originally broadcast on the BBC from 1963 to 1989, over which time seven actors starred as the Doctor. A TV movie, featuring the Eighth Doctor, was broadcast in 1996. However, the TV series would not return until the revival in 2005, continuing to this day.

Big Finish acquired the license to produce audio dramas based on Doctor Who beginning in 1998 with Bernice Summerfield, an expanded universe companion of the Doctor. Soon after, the actors for the Fifth (Peter Davison), Sixth (Colin Baker) and Seventh Doctors (Sylvester McCoy) joined Big Finish to record a series of monthly Doctor Who audio dramas which continues to this day. Though he did not feature in a TV series, the Eighth Doctor (Paul McGann) joined the audio series in 2001, running alongside BBC Book's Eighth Doctor Adventures and Doctor Who Magazine's comics. Employing the vast majority of Doctor Who companion actors across its history, Big Finish were able to produce Early Adventures based on the First (William Hartnell), Second (Patrick Troughton), and Third Doctors (Jon Pertwee), whose actors are now deceased.

In 2011, Tom Baker ultimately joined Big Finish to reprise his role as the Fourth Doctor in his own series of audio dramas.

By 2015, after years of hints toward the new era, Big Finish had acquired the license to produce audio dramas based on the revived series of Doctor Who lasting from 2005, featuring the return of David Tennant as the Tenth Doctor, as well as John Hurt as the War Doctor in a series of twelve episodes before his death in 2017. Initially, the license extended only to the end of the Eleventh Doctor's (Matt Smith) era in 2013. However, since the Twelfth Doctor (Peter Capaldi) was replaced by the Thirteenth Doctor (Jodie Whittaker), the license has extended to include his era as well.

As it stands, Big Finish has produced numerous stories and spin-off series based on Doctor Who, as well as the BBC's televised spin-off series Torchwood and Class.
