releases The Mechonoids proved successful in toys and merchandising, with several models and figures designed and released as early as 1965. They also appeared in a strip in the comic TV Century 21. The final episode of the serial was released as a seven-inch EP by Century 21 Records in April 1966, titled The Daleks; it features new incidental music, additional narration by David Graham, and a recording of the theme music by Eric Winstone. Music and sound effects from the serial were released as part of 30 Years at the Radiophonic Workshop, released by BBC 3D in July 1993. Sound effects were also included on Doctor Who at the BBC Radiophonic Workshop Volume 1: The Early Years 1963–1969, released by BBC Music in May 2000, and sound effects and music were featured on Doctor Who: The 50th Anniversary Collection, released by Silva Screen Records in December 2013 and reissued in November 2014. A novelisation of this serial, written by John Peel, was published by Target Books and W. H. Allen & Co. in 1989 after lengthy negotiations. Peel restored most of Nation's original ideas in the novelisation, as many of the original changes had been due to timing and budgetary reasons rather than artistic ones. The cover was designed by Alister Pearson. The original print of the book was limited to 24,000 copies. Target reissued the novel with a slightly revised cover in July 1991. An unabridged audiobook of the novelisation, titled Daleks: The Chase, was released in August 2011 by AudioGO; it is narrated by O'Brien, with Dalek voices by Nicholas Briggs, and uses Pearson's cover art. The audiobook was reissued in Doctor Who: Dalek Menace! by AudioGO in October 2012. The Chase was released on VHS by BBC Video in September 1993 in a box set titled Doctor Who: The Daleks Limited Edition Box Set alongside Remembrance of the Daleks (1988). The set was packaged in a Dalek tin with a booklet written by Andrew Pixley; Andrew Skilleter designed the cover artwork for The Chase. The serial was released in a DVD box set alongside the preceding serial, The Space Museum, in March 2010; it features an audio commentary with Russell, O'Brien, Martin, and Purves, as well as documentaries about the production, the characters of Ian and Barbara, the appeal of the Daleks and their merchandising, a history of Shawcraft Models, and Cusick's visit to the art
