Bewitched

Bewitched was planned to be reported on in a "new comic for girls", which would be edited by Lady Penelope Creighton-Ward. (PROSE: Time Barrier Busted)

Behind the scenes
Although the reference to "Bewitched" in Time Barrier Busted may seem to be an out-of-universe reference, the intent at the time was that all comics printed in magazines such as TV Century 21 and Lady Penelope took place in the same universe. Thus, "Bewitched" implicitly refers to the in-universe reports provided in the magazine, in a similar vein to at least one reference to Thunderbirds in the magazine.
