From TARDIS Index File, the free Doctor Who reference.

This article is written from the Real World point of view.

TV Century 21 or TV21 was a English publication printing articles and tie-in comics to popular children's adventure series. It was published throughout the 1960s.

Each issue of TV21 passed itself off as a news magazine printed exactly one hundred years in the future. It mainly featured stories based on the puppet television creations of Gerry Anderson, although it also featured the comics later known as The Dalek Chronicles. The Doctor (at that time played by William Hartnell) did not appear in the comic due to rights issue. Apart from this feature, TV Century 21 did not feature any other substantial Doctor Who content.

However, a record, simply entitled The Daleks came out, containing the soundtrack to "The Planet of Decision", the last episode of The Chase, was released as a TV 21 record, with narration by David Graham (one of the voices of the Daleks to explain plot points less obvious without any visuals).

The adventures of the Doctor himself were published in TV Comic. After the Daleks comic had ended, the Daleks would, as they had on television, make appearances as villains in the TV Comic Doctor Who stories.
