Fox News Chicago is running a very interesting experiment - LiveNewsCameras, a site that lets anyone see what any of their news cameras sees at any time.
So as well as the usual array of 24-hour news channels, the site also lets you monitor traffic cameras across a number of US cities; airport cameras at LAX and elsewhere; follow three different live chase cameras; and look at a number of - somewhat eerily deserted - news studios.
Which all raises an interesting question - if the cameras are rolling, why not stick the feed up somewhere and see if anyone wants to look at it? Access to traffic cameras at my own convenience rather than when my local TV news happens to schedule a traffic update would be obviously useful, and in London live footage of the underground stations I use would be helpful too. England is infamous for its infestation of public CCTV cameras - if we must have the things, public online access to the resulting video streams seems like an excellent idea.
