Not really that coincidental… I tried very hard with Google Search and Internet Archive to locate this BBC news archive page.
Was that the first time TiddlyWiki got introduced publicly on mainstream TV program (BBC Click)? 
We have Richard Upstone from the UK to thank for pointing us at TiddlyWiki.
Regular viewers will have heard of wiki before - it is open source server software that allows people to edit the content of a webpage through their browser window.
What TiddlyWiki does is provide a wiki page template that you can download and customise for your own needs at home or work - be it an interactive to-do list, a blog, or your collection of recipes or sporting stats.
