Online Video Watch has a clip of some CNBC presenters trying to figure out what a widget is. I'd make fun of them, except... have you ever tried to define 'widget'? It's not that easy a concept to summarize. (But it's definitely not, as one of the hosts suggests, a virus.)

Anyway, even if the hosts can't figure out what a widget is, their tech guys made a cracking one. If you care about the US stock market -- or about good widgets -- head over to Online Video Watch and have a look.
