Here's a small clip created especially for Octav1us Kitten's Teletext & Digitiser video. The full video can be seen at youtube.com/watch?v=VPp8IivJ7FA

This isn't meant to be a serious explanation of Teletext. In fact, you're best watching the full video to get an idea of why its all a little bizarre. It's especially worth watching if you remember Teletext's digitiser magazine, bamboozle, or just want to know why the BBC version was called Ceefax, rather than Teletext.
