One segment of "The Infinite Quest" was shown each week during "Totally Doctor Who" from 2 April to 29 June 2007. The serial, animated by Firestep, was the second officially licensed, animated "Doctor Who" serial, the first being the flash-animated "Scream of the Shalka" (2003). Missing episodes of the 1968 serial "The Invasion" were also animated for that serial's 2006 DVD release. Both of these animations were produced by Cosgrove Hall. The BBC describes Firestep as "the creative team behind previous "Doctor Who" animated adventures for the BBC." The Firestep website attributes the name to former Cosgrove Hall animators Jon Doyle and Steve Maher.
