The Infinite Quest is an animated serial based on the British science fiction television series Doctor Who. It was made by BBC Television, but does not share the same producers as the live-action series. It was aired in twelve weekly parts (three and a half minutes each) starting 2 April 2007 as a segment of the children's spin-off show Totally Doctor Who. The final instalment (after episode 12) was shown at the end of the "Omnibus" episode, thus increasing the total to thirteen parts, making the compiled series the equivalent length of a standard episode of Doctor Who. The compiled story was broadcast on 30 June 2007, coinciding with the finale of Series 3.
