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, but she had no idea what he was talking about. (AUDIO: The Light at the End)

In 2013, Reece Stanford asked the Tenth Doctor what he watched on television, surprised that he had not heard of Doomcastle. 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.

In the 2010s, when a Cyberman broke into the studios of both Duncan Newmarch and Paul Buckle, the broadcast of the continuity announcements glitched and, momentarily, showed the test card featuring the girl. (TV: )
