History of the test card
The Fifth Doctor tried to tell Nyssa about test cards, after they saw the original 1963 test card on Bob Dovie's television. Nyssa initially assumed that the test card was a coded message, but the Doctor clarified that they were for testing the television picture. The Doctor explained that in 1967, the test card would have an image of a little girl and a clown playing noughts and crosses, but Nyssa had no idea what he was talking about.

In the latter half of the 20th century, the Third Doctor arranged to have the broadcast of the final of Make a Star replaced with the test card, thus defeating 's plan to release yet unwritten songs and unravel the timeline. (PROSE: Hidden Talent)

The Doctor simply responded that he had not watched television "in ages", describing a girl playing noughts and crosses with a clown as the last thing he saw. Reece, however, did not understand.
