The BBC Micro
In the early 1980s, the BBC started what became known as the BBC Computer Literacy Project, initiated partly in response to an  ITV documentary series The Mighty Micro. The BBC wanted to base its project on a microcomputer capable of performing various tasks which they could then demonstrate in the 1981 TV series The Computer Programme. The 'Beeb' computer was very versatile and found many uses in the VT area.
It was used as a clock generator, a logging system and as a matte generator. There are a couple of examples at the bottom of the page from a documentary "Marilyn, Say Goodbye to the President" (1985). Not only did it make the clock(!), but generated the mattes for the title sequence, although the 'explosion' effect was achieved by a Mirage (operated by Grant Watkins!) at Moving Pictures..
